DRV100 - 200 mA low noise laser diode driver
DRV100 - 200 mA low noise laser diode driver DRV100 - Current noise Thorlabs narrow linewidth laser controlled with LD100 laser diode driver and TEC100L TEC controller

Koheron DRV100 drivers are compact, ultralow noise laser drivers, designed to operate narrow linewidth laser diodes. Power supply can be as low as 3 V. They can be directly operated with a switched supply thanks to a very high noise rejection. Laser current can be adjusted with a manual potentiometer.

Spectral density of current noise

The DRV100 laser driver current noise was measured across a 30 Ω resistor for the 40 mA laser current version (A-40) and a 5 Ω resistor for the 200 mA laser current version (A-200).
