Laser Diode Drivers

Our LDD current sources / laser diode drivers cater for a variety of applications. The drivers support different operation modi (CW, modulated, QCW, pulsed).

The latest laser diode drivers LDD-1124, LDD-1121 and LDD-1125 are members of the digital LDD-Family and feature a microcontroller and a FPGA.

There is an LPC option available allowing closed-loop Laser Power Control. LDD-Family drivers are also available as High Voltage (HV) hardware versions for special requirements.

Our LDDs are ideally complemented with our TEC-Family precision Peltier temperature controllers.
