The LTC100 Series is a complete laser diode and temperature controller set including mount, optic and accessories. It combines the benchtop LD Current Controller LDC205C and the benchtop Temperature Controller TED200C and other required items for a stable and safe operation of standard laser diodes.

The kit is offered in three versions depending of the anti-reflection coating of the collimation optic: LTC100-A for 400 - 600 nm, LTC100-B for 600 - 1050 nm and LTC100-C for 1050 - 1550 nm. For detailed information about the components, please see the links to the product pages of the components list above. Each unit ships with two cables, one for the temperature controller (CAB420-15) and one for the laser diode controller (CAB400). Although all necessary cables are packaged with the purchase of the controllers and starter sets presented above, replacements can be purchased separately.

The TED200C and LDC205C operate with a line voltage of 100, 115, or 230 VAC. These sets are shipped with imperial mounting posts and holders. The mounting base is compatible with both imperial and metric systems. If you prefer metric posts and holders please contact our tech support team: see our contact page.

^a Temperature Control data for thermistors are given in Ω since the controlled parameter is the resistance, not the temperature
^b Due to the nonlinear conversion from Ω to °C the stability in °C depends on the operating conditions and the characteristics of the thermistor. E.g. for a typical thermistor at a set point of 10kΩ (25°C), a 0.5Ω stability translates into about 1mK temperature stability. At a set point of 5kΩ (38°C), the stability is about 2mK.

All technical data valid at 23 ± 5 °C and 45 ± 15% rel. humidity

Hi, is this Laser Diode Operation Starter Set compatible with short wavelenght laser diodes, for example, HL40023MG? If so, then the accessories for 600-1050 nm or 1050-1550 nm are not needed, right? Thanks,

A response from Julien at Thorlabs: Hello. Yes this is correct. If you would like to have more information about those laser diode drivers and their compatibility, please feel free to contact us a techsupport@thorlabs.com

Hello, So I can use LDC205C and the TED200C with the mount LM14S2 and laser diode FPL1053S. Is that so ?

A response from Julien at Thorlabs: Hello Lalit, this diode will work fine with the LDC205C and the TED200C which are comprised within the LTC100-C and a LM14S2

Hello Thanks for the reply. We are planning to use FPL1053S laser diode alongwith LM14S2 and LTC100-C . Are they compatible according to the TEC specifications as you said LM14S2 does not has TEC element ? Regards Lalit

Poster: jvigroux

Posted Date: 2012-01-09 04:12:00.0

A response from Julien at Thorlabs: Thank you for your inquiry. The controllers Laser diode driver and temperature controller) used in the LTC100 are directly compatible wit the LM14S2 and support all hardware features of this mount. Please note that the LM14S2 does not contain any TEC element as those are normally integrated within the butterfly mount such that in order to check the compatibility of the temperature controller with your system, one would need to check the specs of its TEC element.

I want to know whether LTC100-c is compatible with LM14S2(Butterfly Laser Diode Mount). Regards Lalit

I would like to use a similar kit with diode laser of hig her power, about 1 W. Is it possible to replace the LDC205C driver by the LDC220C one? In this case, how can I obtain a cotation? Best regards Djalmir N Messias
