DRV100 Low noise laser diode driver
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.

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).
