LDC200Cシリーズの半導体レーザーコントローラは、非常に優れた性能を発揮します。ご提供可能な7つのモデルは、それぞれ異なる電流範囲に対応し、各製品はその特定の用途に適切な性能を実現するように構成されています。各ユニットには完全試験報告書と校正証明書が添付されています。製品情報の詳細については、「仕様」タブと「セレクションガイド」タブをご参照ください。

当社ではこれらのコントローラを24か月ごとに校正することをお勧めしております。当社では再校正サービスを提供しております。詳細は当社までお問い合わせください。

モード

LDC200Cシリーズの半導体レーザーコントローラでは、半導体レーザを定電流(CC)モードあるいは定光出力(CP)モードで駆動できます。全ての半導体レーザと フォトダイオード搭載型の製品に対応しています。半導体レーザは、常にグラウンド接地を基準として駆動されます。フローティング接地型のコントローラと比較して、このグラウンド接地はノイズ、過渡抑止と安定性の面で優れています。

定電流モード
定電流(CC)モードでは、レーザへの電流は設定されたレベルに厳密に保たれます。このモードは、低いノイズと速い反応速度が必要とされる場合に使用されます。このモードを使う用途では、殆どの場合に温度安定化も要求されますが、当社では、最大値12 WのTED200C最大値225 WのTED4015の2つの温度コントローラの製品をご提供しています。

定光出力モード
定光出力(CP)モードでは、殆どの半導体レーザーパッケージに内蔵されているフォトダイオードからの信号を利用してフィードバックすることによりレーザ出力を安定化します。CPモードでは、フォトダイオード電流のフルスケールを調整することにより、個々の半導体レーザにおけるフォトダイオードの電流の違いを補償しています。

コントローラの使用

直感的かつユーザーフレンドリな操作
選択された動作モードに関係なく、5桁のLEDデイスプレイではレーザ電流、フォトダイオードのモニタリング電流やレーザ電流の限界値を表示することができます。また光出力をmWの単位で表示することも可能です。出力計測値は、前面パネルの調整用ポテンショメータでモニタ用フォトダイオードの感度に対応して校正できます。多くの用途では、前述の利点によって、別個の光パワーメータは必要ありません。

背面パネルからの制御
ユニットの背面には、レーザ電流または光出力用の変調入力端子(半導体レーザのパルス出力に使用可能)、電流に比例する出力端子、そしてリモート制御でレーザON/OFFするTTL入力端子があります。

保護特性

電流リミット
電流リミットは精密調整できるので、レーザ電流が最大値を超えないように調整できます。調整ミスを防ぐために、当社では意識的にこの部分の操作の実行が難しくなるように製品設計しました。予め設定された値より大きなレーザの駆動電流を供給しようとすると、表示と音声で警告します。外部変調機能を利用する場合でも、予め設定された値を超える電流供給はできないようになっています。

電流電源
電流電源と半導体レーザ間の接続が遮断されると、電流電源は自動的に電流の出力をスイッチOFFします。電流回路がオープンになると、LEDが「OPEN」と表示し、短い警告音が鳴ります。独立したレーザONのキースイッチにより、レーザ電流をON/OFFできます。スイッチがOFFになると、LDC200C内の電子スイッチが、半導体レーザを短絡させて確実に保護します。スイッチがONになった時には、ソフトスタートが実行され、過渡電圧無しで電流がゆるやかに増大するようになっています。ライン故障が起こっても、レーザ電流は過渡的な影響を受けません。ACラインにおける電圧ピークは、電気フィルタ、トランスの遮蔽、適切な筺体の接地により抑制されます。

接続ケーブル

当社の半導体レーザーマウントにLDC200CシリーズのLDコントローラを接続するためには、ケーブルCAB400が必要です。各コントローラ本体にはケーブルが1本付属しています(長さ1.5 m)。追加のケーブルも下記にてお買い求めいただけます。

I am using LDC205C, but I cannot adjust the I_LIM (current limit). It is always 100 mA. Is there anything I should pay attention to? How can I adjust the current limit? Thanks a lot!
wskopalik  (posted 2021-02-25 04:30:05.0)
Thank you very much for your inquiry! The current limit can be adjusted using the potentiometer “LIM I” on the LDC205C. First, set the display to "ILIM" using the arrow buttons. It will then show the set current limit. Then use a screwdriver to set the desired current limit by turning the potentiometer "LIM I". It is the safest to switch the laser current off during the adjustment. I will also contact you directly to provide further assistance.

Hello, I am using the LD205C. Is there a way to measure the voltage applied to the LD when driving in current mode? (looks like there are voltage readout pins on CAB400, I'm wondering if these could be redirected to a voltmeter?)
MKiess  (posted 2020-10-02 08:16:16.0)
Hello, thank you very much for your inquiry. The LDC205C does not allow you to check the voltage via the 9-pin connector. The pins of the CAB400 are not connected on the LDC200 series. With the LDC4000 series controllers and the PRO8 laser diode current control modules you have the possibility to measure the laser voltage.

Hi, Is the LDC205C compatible with a LD with a floating anode (in a butterfly type 2 with bias T package)?
nreusch  (posted 2020-06-15 03:46:26.0)
Thank you for your inquiry. Yes, you can drive floating laser diodes with the drivers of our LDC series. As settings for the laser diode output configuration, you can either use AG or CG polarity. Please carefully check that the pin assignment of your diodes is compatible with the pins of the LDC driver that are shown in the Pin Diagram tab.
wenzel.jakob  (posted 2017-11-28 19:28:38.723)
Dear Thorlabs support, a minor question that wasn't clear to me from the documentation: do the LDC* controllers persist the current/regulation settings when they are powered off and turned on again at a later point? Or does the entire configuration have to be repeated each time? The same question also applies to your temperature controller TED200C. Thank you!
swick  (posted 2017-12-01 03:34:43.0)
This is a response from Sebastian at Thorlabs. Thank you very much for the inquiry. When nothing is changed at the control panel, the current limit, current set point and other settings will not vary when power cycling the LDC drivers. Same is valid for TED200C.

Hi I'm using LDC205C w/ TCLDM9. I wonder if it is possible to connect directly to PD output of a laser diode? I want to record and process signal from photodiode rather then monitoring it's current with LDC.
mvonsivers  (posted 2017-11-27 09:19:18.0)
This is a response from Moritz at Thorlabs. Thank you for your inquiry. To monitor the PD signal externally you would need a custom cable which is connected to pins 2 and 4 of the "LD Driver" connector on the TCLDM9 mount. I will contact you directly for further details.

Hi Thorlabs, I am using a LDC202C current source in constant current mode, and find that the I_LD_SET changes over time. As I am using a function generator to control the current source, when I_LD_SET changes, the current output also changes. Could you explain me what is exactly the I_LD_SET and what will affect its value? I can't find much information about it on the manual. Thanks.
mvonsivers  (posted 2017-08-17 04:04:32.0)
This is a response from Moritz at Thorlabs: Thank you for your inquiry. When modulating the current with an external voltage source, I_LD_SET is an offset value that can be changed using the control knob. I will contact you directly for further details.

Hi, we have some problem on your LDC240C current source. The current source was in normal use (~1.3A, connected to an AG laser diode) but suddenly generated a buzzer sound and stopped working in the last week. The current source has no output current and the LED display shows "-----" when selecting ILD. However, the display of ILIM is normal. Can you give us some suggestion?
mvonsivers  (posted 2017-08-17 06:18:11.0)

Dear Thorlabs, is your laser diode driver LDC205C compatible with laser ’PLT5 520_B1_2_3’ with built-in photodiode? How can I connect ’PLT5 520_B1_2_3’ with photodiode in reverse bias mode?
swick  (posted 2017-05-15 03:21:52.0)
This is a response from Sebastian at Thorlabs. Thank you for the inquiry. This Laserdiode is compatible to LDC205C and has Pin Style A (LD Anode and PD Cathode connected to Ground). If the Photodiode shall be operated with bias voltage, a battery can be connected in series to the Photodiode. You can find further information in the manual of LDC205C on page 12. I will contact you directly to provide assistance.

Would it be possible to have a strain relief version of the CAB400? I like the SR9 cables a lot, but changing the diode drive to one with TEC meaning I have to give them up. The CAB400 in comparison is too rigid.
swick  (posted 2017-03-31 03:06:09.0)
This is a response from Sebastian at Thorlabs. Thank you very much for the feedback. At the time we do not offer Strain Relief Cables for laserdiodes based on CAB400. We will internally discuss this idea.
user  (posted 2016-10-11 13:48:19.68)
Why is the current listed as ±? It doesn't make sense to me to be able to reverse the current. For one thing the LD won't function and can be damaged by reversing leads. In fact other LD drivers will switch off if you attempt to energize with reversed leads, which is a useful safety feature. Does this model have that feature?
swick  (posted 2016-10-13 03:28:48.0)
This is a response from Sebastian at Thorlabs. Thank you very much for your inquiry. The ± is referred to the feature Anode Grounded (AG) and Cathode Grounded (CG). While keeping the Compliance Voltage positive the Electrical Current has to be positive for CG and negative for AG. For LDC-Series if the laser diode was connected correctly but the polarity of the laser diode was selected wrong, an “OPEN” error will be indicated. After pressing "LASER ON" the LED "OPEN" extinguishes and the output can be switched on by pressing "LASER ON" again.

Dear Thorlabs, is your laser diode driver DC201CU compatible with your LED sources, e.g. LED631E? We need a very stable current driving for a LED and we have such a laser diode driver. I suppose we can use it, cannot we? Best regards
shallwig  (posted 2015-12-14 05:10:02.0)
This is a response from Stefan at Thorlabs. Thank you very much for your inquiry. The LDC201CU can deliver up to 100mA constant current at 5V compliance voltage. The LED631E can be driven up to 50mA (max rating) at typically 2.2V. You can find these information in the spec sheet of the Driver http://www.thorlabs.de/newgrouppage9.cfm?objectgroup_id=10&pn=LDC201CU and LED http://www.thorlabs.de/thorcat/16200/LED631E-SpecSheet.pdf You can use this driver in “constant current” mode to run the LED. There is no ready to use mount for these LEDs available, for correct connection please check the Pin assignment of CAB400 cable: http://www.thorlabs.de/newgrouppage9.cfm?objectgroup_id=10&pn=LDC201CU The Interlock Pin 1 and pin 5 must be connected externally by a short cut wire, by a circuit (total resistance <430 Ohm) : The current limit should be set at the ILim potentiometer to maximum 50mA. Please also take care of the soldering specifications which are mentioned in the LED spec sheet as well as correct pin assignment. I will contact you directly to check if there are any open questions.

Dear Madam or Sir, I currently have an LDC210C and want to drive an FPL1009P laser diode on an LM14S2 mount. I would like the diode to deliver a pulse with a frequency of 10MHz. Can I achieve this with the external modulation input? Thank You.
tschalk  (posted 2015-03-04 09:28:59.0)
This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. The bandwidth of the analog modulation input of the LDC210C is DC to 100kHz and a modulation of 10MHz is not possible. But the laser mount LM14S2 provides a RF modulation input (BIAS-T) for an external modulation up to 500MHz. You can find more detailed Information in the corresponding Manual at RF Modulation: http://www.thorlabs.de/thorcat/10600/LM14S2-Manual.pdf

Dear Madam or Sir, I am using an LDC202 to drive a diode laser, and I would like to protect the diode when the controller is not connected or not working using a shorting Reed relay. This relay would be driven with the 10mA current available through the interlock pins 1 and 5 while the laser is "on". To do this I would need a voltage of the order of 5V between pin 1 and 5, but instead I found about 2.3V. Is there a possibility to increase this voltage to about 5V. Thank you, Gabriele Ferrari
tschalk  (posted 2013-10-24 06:13:00.0)
This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. The interlock is not designed to be used as an external signal. Because of the internal logic circuit its not possible to provide the signal you would need for your application. I will contact you directly with more detailed information.

olsonaj  (posted 2011-10-02 10:30:21.0)
Have had this controller for a couple years. An issue I've had is the front current control knob is very loose, and makes it hard to tune the current precisely (esp. important for manually current-tuning the wavelength of a diode laser). Also, at times the knob seems "loose" and the current will jump around between different values. Perhaps this is a faulty connection? On future designs I recommend a sturdier current control knob.

I have a big issue with this kind of driver. Up to now, I used a home-made driver that was built many years ago. Nevertheless, I needed a less noisy source, so I bought this. I tried to plug my laser diode (HL 6320G), following each documentation (of the diode, AG, following the pins correctly ; of the current controller, connecting the right pins to their right place, chose properly the polarity on the driver, set the limit for the current to 70 mA, put the knob to the left,...) : and when I push "laser on", when no current, its ok. But as soon as I get 0.1 mA, the open lights up, and no current anymore. I tried other cables configurations, verified that my diode works (with the old controller). Whats wrong ? Has anyone experienced that ? Bests

A response from Juergen at Thorlabs to joonggun.ha: This error message indicates a hardware failure. From experience it is known to us, that in 99% of such cases the reason for this failure is operation of the item at 230V AC while it was set to 100/115V AC. Of course, mains fuse blows, however during fuses reaction time damages to electronic circuitry may happen. After replacement of mains fuse and setting to correct AC, the unit switches on, but indicates only "Err.05", no operation is possible. The unit must be returned for repair to Thorlabs, this repair is NOT covered by warranty as the unit has been used inappropriate: We put an eyecatching yellow sticker accross the AC power connector on the rear panel, alerting the operator "Use correct voltage setting and fuse - see manual". So prior to apply AC voltage, this sticker must be removed. Please contact the Sales office, from where it has been purchased, for return instructions.

Hi Ina, Thank you for your feedback. Manual and web specs are correct - LDC201CU is an ultra low noise driver. This is achieved by a low pass filter on the current output. Due this LPF, the max. modulation frequency in CC mode is 200Hz (-3dB, small signal) In VOL19, p.419, spec table, 200kHz is stated, which is wrong. We will correct that. Juergen Hartmann

Hi, there is a typo both on this webpage and the operation manual that comes with this laser diode controller (p. 37): The small signal 3dB bandwidth (cc mode) goes up to 200kHz, not 200Hz. Thanks
