High Power Pulsed Laser Diode Driver

A pulsed laser diode driver is a voltage controlled constant current source which is designed to deliver a repeatable set of current pulses at a set output level over user defined time intervals.

These are by no means standards just a generalization based on the author s experience in the laser diode controller world. What is a pulsed laser diode driver. High power laser diode driver 36 v 21 a with tec air cooling high power laser diode from 10 to 150 w at 808 915 976 or 1064 nm high speed laser diode driver with user design nanosecond pulse shape.

They offer a pulse duration of 20 microseconds to 3 milliseconds with an average power of 1 killowatt. A high power laser diode driver is 5 amps and up to 100 s of amps in a cw mode. A switching element is connected between the other end of the diode array and ground. These ultra high power laser diode drivers from quantel offer up to 500 amps of output current and up to 100 volts of compliance voltage.

Ideal for r d or manufacturing testing precision low noise current control with set point accuracy of 0 1 of reading is delivered to the lasers with four wire voltage measurement and a photodiode monitor with adjustable reverse bias for cw and qcw liv testing laser. Ldx 36018 35 laser diode driver high power cw qcw 18a 35v gpib. To understand the basic building blocks of a semiconductor laser driver please refer to our article on continuous wave drivers. Pulsed laser diode drivers allow for the modulation of a laser diode using by varying the laser drive current.

Each ldx 36000 series laser diode driver was designed as a current source specifically for high power laser diodes. With output currents to 200amps the lddhc series high power laser diode driver is available in 3 power levels and a wide range of compliance voltages. Their are kw level drivers available in pulsed and qcw mode versions. A shunt switch is connected across the diode array.
