 (posted 2025-01-26 18:58:37.667) Hi. I wanted to enquire whether these and the TEC driver ICs are vacuum compatible. If so whether any extra heat dissipation mechanisms are required? jjadvani
 (posted 2025-01-27 08:32:26.0) Dear Ishan, thank you for your inquiry. These TEC driver and evaluation board are made of PCB which will outgas in vacuum. So, these are not vacuum compatible. ChaeWon Kim
 (posted 2023-12-01 14:15:32.7) Hello. I wonder if the MLDEVAL board and L980P010 diode are compatible. When I look at the website, it says they are compatible, but when I look at the board, I can't see the part where I can plug in the diode. Can I purchase and use another adapter in this case? Or can I just plug it in and use the laser? I'll wait for the answer. thank you. dpossin
 (posted 2023-12-06 05:09:30.0) Dear Chae Won Kim,
Thank you for your inquiry. The MLDEVAL board alone is not feasible to drive laser diodes. You additionally need an suitable laser mount. For the L980P010 for example, the LDM56/M would work. I´ll reach out to you to discuss your application in more detail. user
 (posted 2022-07-18 12:30:55.417) Are the formulas for the relation between laser diode current and setpoint control voltage correct on the page 8 in Data sheets of Laser Drivers MLD203CLN and MLD203CHB?
If setpoint control voltage is +2.5V, laser diode current would be 0.0002A (200uA ). dpossin
 (posted 2022-07-19 04:45:13.0) Dear customer,
Thank you for your feedback. Yes you are right. The formula there is not entirely correct. Instead of 12500 ohms it should read 12.5 ohms of internal resistance. We try to correct this typo in the future. Sorry for the inconvenience! Peter Johnston
 (posted 2022-04-14 13:37:38.027) The MLD203 datasheet is incorrect for the set current formula. It should be I_LD = V_SET/12.5, not 12500! Please update! mdiekmann
 (posted 2022-04-22 02:47:31.0) Thank you very much for your feedback! We are looking into an update of the manual. Tony Pugatschew

 (posted 2022-04-01 09:23:32.0) Dear Tony,
Thank you for your feedback. I am reaching out to you in order to provide information how to correctly set up the MLD203CHB. Manuel B.
 (posted 2020-09-23 22:05:28.4) The drivers works really great but the compliance voltage is really low. Is there any way to increase the voltage up to 5V by changing VIN2 or adding an offset voltage source? I want to use these drivers with the L405P20, PL450B and possibly L520P50, which all consume less than 200mA but the operating voltage is larger than 3V. Thanks nreusch
 (posted 2020-09-25 06:27:38.0) Thank you for your feedback. The current models of our MLD series are not designed to provide up to 5 V. As there have been several inquiries from customers for higher compliance voltage MLDs, we will evaluate internally whether we would be able to offer such drivers in the future. They will, however, not be available on short time scales. I will contact you directly to check your requirements and time schedule in detail. In the meanwhile, you could probably use one of the other OEM or benchtop drivers like IP250-BV or LDC202C. 寛之 遠藤
 (posted 2019-10-10 16:24:06.81) 現在、MLDEVALを用いてLDを駆動させようとしておりますが、LD出力が非常に急峻に変化してしまい、正常に動作させることができません。

 (posted 2019-10-10 05:29:21.0) This is a response from Wolfgang at Thorlabs. Thank you for your inquiry!
We will contact you regarding your issues with the MLDEVAL. Jan Soukup
 (posted 2019-04-09 17:23:00.687) How can I drive a green laser diode that needs a 5.4 to 7 Volts operating voltage from MLDEVAL with MLD203P1E.
Thanks Jan swick
 (posted 2019-04-18 04:18:19.0) This is a response from Sebastian at Thorlabs. Thank you for the inquiry. The MLD203P1E is designed for driving light sources in constant-power mode by regulating electrical current so that optical output power stays stable. The signal to which the driver regulates to needs to be generated by an optical sensor. An other point is that MLD203P1E works up to 200 mA and 3V which is is not suitable for LEDs with 5.4 to 7 V. I contacted you directly to provide further assistance. seungbum-yang
 (posted 2018-10-18 23:54:32.023) I am using MLDEVAL evaluation board with MLD203P1.
most of the time it is OK. but sometimes, It feels like the laser is fluctuating periodically. the period is usually in few second scale, mostly about 4 sec.
I have checked this through checking correlation from laser speckle image.
Is there any reason that you know of regarding the laser fluctuation in period? swick
 (posted 2018-11-02 04:52:49.0) This is a response from Sebastian at Thorlabs. Thank you for the inquiry.
The issue you are reporting sound like a drift which might be related to a non-stable temperature of the laserdiode.
This effect could be based on many parts within the setup.
I contacted you directly for troubleshooting. dreader
 (posted 2018-06-07 08:46:48.657) Hi, the comments in your feedback section suggest that some customization may be possible to achieve a higher compliance voltage. If so, can you tell me more about it? mvonsivers
 (posted 2018-06-12 06:30:40.0) This is a response from Moritz at Thorlabs. Thank you for your inquiry and the interest in our products. I will contact you directly to discuss our options for customization. eileenscannelll

 (posted 2017-10-16 03:45:53.0) The MLD 3V compliance Voltage is too low for the Blue and UV diode. If you can raise it up to 8v, what's the maximum current available? swick
 (posted 2017-10-20 03:49:33.0) This is a response from Sebastian at Thorlabs. Thank you for the inquiry. We do not offer MLDs with compliance voltage of 8V. Alternatively you can use LDC202C, LDC205C or LDC210C which have compliance voltage of 10V. ludoangot
 (posted 2017-04-18 16:32:11.083) Would it be possible you consider making such a driver with the same efficient design and ease of use but with higher maximum current and compliance voltage? swick
 (posted 2017-04-19 03:11:04.0) This is a response from Sebastian at Thorlabs. Thank you for the feedback. We can modify our MLD modules for custom applications with different current and voltages ranges.
I will contact you directly to discuss further details. ludoangot
 (posted 2016-09-23 12:14:49.8) Hello, can the drivers be used in a parallel configuration to increase the output current? And how does the circuit behaves when the compliance voltage is reached and exceeded? swick
 (posted 2016-09-27 10:14:16.0) This is a response from Sebastian at Thorlabs. Thank you very much for your questions. The Constant Current Laser Drivers (MLD203CLN and MLD203CHB) can be paralleled to increase output current.
For optimal load sharing an additional load resistor can be added.
When the compliance voltage is exceeded the maximum output current will decrease. cbrideau
 (posted 2016-09-14 16:33:47.54) What enclosure does the MLDEVAL fit in? swick
 (posted 2016-09-15 05:41:39.0) This is a response from Sebastian at Thorlabs. Thank you very much for your feedback.
We have developed this evaluation board to offer a multifunctional tool to test products of our MLD Series before a PCB has to be designed for integrating our modules into specific applications.
Therefore the MLDEVAL is made for evaluation purposes. It provides rubber feet to ensure stable stand on a laboratory table without the need of extra housing.
For OEM customers we can offer customized application boards, which fits perfectly to customized housings. mitch
 (posted 2016-08-28 07:02:00.877) Hi, this new product look extremely useful - thanks! I would like to use the constant power version with my own custom bias-T for analog modulation. Is this device compatible if I were to connect a bias-t (perhaps your one) between the LD and the GND_LD or LDA pin? I prefer to use type A laser diodes. Thanks swick
 (posted 2016-08-29 04:32:32.0) This is a response from Sebastian at Thorlabs. Thank you very much for your inquiry.
Using a Bias-T with our Constant Power LD Driver (MLD203P1) will not work, because it would disturb the internal regulation of the output power. Modulation of MLD203P1 can be done by modulating P-Set(input) with approx. 1-50 kHz.
With our Constant Current Drivers (MLD203CHB and MLD203CLN) it will work to use a Bias-T for modulation.
I will contact you directly to discuss your application in more detail. ludoangot
 (posted 2016-08-25 12:00:59.203) Is there any limitation to using these to drive LED (providing the LED complies with the driver's specs)? Also, I totally second the previous comment. A blank or pre-soldered PCB for fast prototyping with these drivers would be very welcome. Ideally with the option to plug said PCB into common breadboards (0.1 in pitch). swick
 (posted 2016-08-25 03:11:58.0) This is a response from Sebastian at Thorlabs. Thank you very much for your inquiry.
It will work to drive LEDs with MLD203CHB or MLD203CLN if all important parameters of the LEDs are due to the controller's specification. Most limiting factor for driving LEDs with MLDCxx modules will be the compliance voltage, which is typical 3 V.
Regarding the PCB for fast prototyping, we will release an evaluation board during next weeks. Together with the evaluation board we will release the requested adapter plug with 0.1 in pitch pin headers for direct use in breadboards. cbrideau
 (posted 2016-08-17 14:14:42.88) A version of these pre-soldered on a break-out PCB with protoboard tinned holes sized to fit into one of the EEB enclosures would be very helpful for DIY assembly. swick
 (posted 2016-08-18 08:42:45.0) This is a response from Sebastian at Thorlabs. Thank you very much for your feedback. We will look into this, discuss your suggestion internally and contact you directly by email. |
