DRV100 Low noise laser diode driver DRV100 Low noise laser diode driver current noise DRV100 Low noise laser diode driver Thorlabs narrow linewidth laser controlled with DRV100 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.
