Package Weight: … We like to use this model for our single emitter type diode testing, but our newer high power products are starting to push 40 A + and we have had to look for higher power alternatives. They allow space-saving simultaneous current and temperature control of a laser diode with a single module. The soft start feature ensures a slow increase of the laser current without voltage peaks after the device is switched on. If possible to get the value, let me know whether you have some program you provide or some sample coded by Labview. Thank you very much. Integral control goes a step further than proportional gain, as it is proportional to not just the magnitude of the error signal but also the duration of the error. These modules can also be modulated, externally or internally. Firmware version: 3.30. The LDC4000 Series of Laser Diode Current Controllers provide precise and stable current for driving high-power laser diodes with injection currents up to 20 A. Dear Thorlabs Team, It is totally new. If the connection between current source and laser diode is interrupted, or the laser voltage exceeds the adjustable voltage protection threshold, the laser current is switched off. The TCLDM9 mount is ideal for temperature-controlled operation of all Thorlabs' 3-pin and 4-pin laser diodes in Ø9 mm and Ø5.6 mm TO Can packages. This is the input screen for the Quasi-Continous Wave (QCW) pulse mode settings, e.g. We also provide loose 13W3 connectors for customers who wish to make their own cables. In general the gains of P, I, and D will need to be adjusted by the user in order to best servo the system. As the SP is reached [e(t) approaches zero], the circuit will decrease the current through the TEC in anticipation of reaching the SP (derivative control). The laser diode controllers of the series LDC200 by Thorlabs GmbH are extremely precise controllers for laser diodes and LEDs. Thank you very much for your feedback! Helmut Mäckel.
