(posted 2023-08-18 04:17:05.0) Hello Shiva, thanks for reaching out to Thorlabs. Yes we can offer the bias tee adapter PCB component separately as a special quote in case it's been lost or damaged. In these cases we would recommend you to contact techsupport@thorlabs.com directly, and I've reached out to discuss your application further detail. user
(posted 2023-05-18 17:18:29.64) Hello! We want to use LM14S2 mount with LDC8005 and TED8020, but we find that the pin configurations of LM14S2 and LDC8005 are different, the pin3 of LM14S2 is Laser Diode Anode and pin3 of LDC8005 is Laser Diode Ground, while the pin8 of LM14S2 is Not Used and the pin8 of LDC8005 is Laser Diode Anode. Do I need to swap the connection of pin3 and pin8 of the cable when using them together? cdolbashian
(posted 2023-05-26 12:55:51.0) Thank you for reaching out to us with this inquiry. As the butterfly diodes are Anode grounded, the pin 3 and pin 8 have identical electrical paths. You shouldn't need to swap any connectors. I have contacted you directly to discuss this in more detail. user
(posted 2022-04-15 10:19:25.907) Hello! Could you please tell me if the LM14S2 is thermal vacuum compatible? cdolbashian
(posted 2022-04-20 04:40:50.0) Thank you for reaching out to us with this inquiry. I have reached out to you directly to discuss the specific vacuum environment in which you are intending to place this device. Ben Griffiths
(posted 2022-02-02 10:30:38.233) Hi, I see that the bias-t provided in the LM14S2 is spec'd to 500 MHz. Ideally I would like to drive an RF signal at several GHz, do you offer a bias-t that could handle this higher rate to fit this mount? ksosnowski
(posted 2022-03-02 11:44:48.0) Thanks for reaching out to Thorlabs. Unfortunately we currently do not offer any drivers or mounts that can achieve these higher speeds. In the past, we have recommended using drivers and mounts offered by AV Tech (which is not affiliated with Thorlabs in any way). An alternative option to modulate at higher frequencies is to use an external source such as a LiNbO3 EO modulator. I have reached out directly to discuss your application further. Rebekah Olson
(posted 2021-07-09 11:35:35.067) I'd like to see a high-powered version of this mount to go along with products like the ITC4005. Some pump diodes have much thicker pins that make them incompatible with this version. YLohia
(posted 2021-07-09 02:54:54.0) Hello, thank you for your feedback. I have posted your suggestions on our internal engineering forum for consideration as a future product. Wieslaw Jasiewicz
(posted 2020-11-14 10:23:38.04) Hi,
I can not find main PCB wiring and parts (U1) specification within LM14S2 documents.Would it be possible to get it as it is necessary for our application?
Regards

(posted 2020-02-27 04:12:04.0) Thank you for your feedback. At the moment, we do not have a butterfly laser diode mount with external case temperature control. I have added this idea to our internal product forum for discussion to offer this at a future time. Matthew Majewski
(posted 2019-09-26 22:07:42.733) Hello,
I understand that the bias-T adapter supplied will only work with diodes that have the correct internal circuity, but my question is if it would be possible to use your laser diode bias-T PCB component to externally wire up a modulation input for other diode types? asundararaj
(posted 2019-10-02 11:05:27.0) Thank you for your Feedback. To use the Bias-T adapter with other configurations of diodes in a Butterfly package, you can manually configure the LM14S2-UA to suit the pin configurations of your diode. HYUNJONG CHOI
(posted 2019-08-27 17:56:47.8) Nice to meet you.
I'm try to find the evaluation board of thorlabs CW laser "SFL1550P". In the manual of SFL1550P, LM14S2 will be used for mounting the laser SFL1550P. Is it mean that LM14S2 can be used for the evaluation board of SFL1550P? Please reply. Thank you
Your sincerely,
Choi YLohia
(posted 2019-08-27 09:25:51.0) Hello Choi, thank you for contacting Thorlabs. The LM14S2 is intended to serve as a proper mount for butterfly laser diodes and can be used for nominal testing of the SFL1550P. I have reached out to you directly to gather more details about your application and requirements. bsvikram
(posted 2017-05-23 01:24:29.873) Hi, We want to use bias-t to modulate the current of a type -1 diode (SFL 1550S). But the manual says that the bias tee is for type-2 diodes only. How can we modulate type -1 diodes at high frequencies. We also have CLD 1015, but it is also limited in modulation frequency range. nbayconich
(posted 2017-06-09 09:33:29.0) Thank you for contacting Thorlabs. The bias-T adapter in the LM14S2 is only compatible with Type 2 Telecom Laser Diodes. Type 2 telecom butterfly diodes are designed specifically to be modulated by a bias-T RF circuit. The type 1 butterfly diode packages do not have the proper circuitry in order to be modulated in a bias-T circuit.
Some alternative options to modulate your Type butterfly diodes at higher frequencies is to use an external modulating source such as a LiNbO3 EO modulator which can modulate up to 40 Gb/s .
Several of our Laser Diode current drivers can directly modulate the type 1 butterfly diode mounts through the LM14S2. For example the ITC series controllers can directly modulate from DC to 150Khz. A Techsupport representative will contact you directly with more information. savin.saju

(posted 2014-12-10 05:07:40.0) Response from Jeremy at Thorlabs: We do not have a spec on the maximum heat capacity but it is estimated to be around a few W. We will contact you directly to discuss more about suitability of the mount with your application. emsia
(posted 2013-11-19 10:52:41.403) Dear Sir/Madam,
I am using ILX LDC to control my laser mounted on LM14S2. Everything works perfectly except when the laser is on, the LED does not turn on. The intelock is on bypass mode.
The pin 1 os LD is connected to intrlk of the ILX LDC and pin 5 to the ground.
any suggestions would be appreciated.
Thank you jlow
(posted 2013-11-19 09:23:30.0) Response from Jeremy at Thorlabs: The LED indicator needs a certain amount of current (5-10mA) to turn on. We will get in touch with you directly to troubleshoot this. thomas.chassagne
(posted 2013-07-02 15:29:14.367) Hi, I would like to use the LM14S2 with the TED200 TEC controller and an external electronic board that command the bias current.
In order to disable the Status and the Interlock function, Should I switch the TEC Lock button to "Bypass" ?
In the Operating Manual, it's said that a resistor should be used to limit the curent into the PIN1 to between 5. Thus, if I connect the "driver" side of the resistor to 5V, I should use a 500Ohm resistor and connect the PIN5 to the ground ?
Thanks, Thomas tcohen
(posted 2013-07-11 16:20:00.0) Response from Tim at Thorlabs to Thomas: Thank you for contacting us. Yes, it should be switched to Bypass. You can use that resistance but you may use slightly higher as the current should be limited to a maximum of 10mA. mlaroton
(posted 2013-03-14 10:48:56.47) Hi, I would like to use the LM14S2 mount with the FLD5F10NP-A Modulator-integrated DFB laser.
In this laser, the case ground is the laser cathode.
I wonder if I can still use your mount; do I need a non-standard Adapter Card? or does this feature prevents me to use your mount at all? Thanks, Miguel. tcohen
(posted 2013-03-14 13:22:00.0) Response from Tim at Thorlabs: Physically it appears as if your modulation connection opposite to the pins would interfere with our package designed for a 14pin butterfly. Even if this were to fit however, and a custom configuration card LM14S2-UA was to be used, the LM14S2 is suitable only for anode-grounded diodes. jjurado

(posted 2009-09-09 09:24:44.0) Dear Sir/Madam:
We are using LM14S2. Recently we found the current waveform of DFB LD was not stable. The current drive seems to be OK. Since it is new one and I tested with two simulated diode in series. There was no problem. But when I connected to the LD. The current waveform ( monitored from the current feedback)was not constant. Even worst, after a period of fluctuation, it kept decreasing and finally went down to zero. Sometime, if I switched off the driver and powered up again. The current recovered. The LD is the NEL with a little difference layout of pin to type two laser. I am using type 2 configuration card with pin12 connected as the instruction from the manual. What ,do you think, is the reason? |
