CW and Quasi-CW Laser Diode Drivers

DEI offers a variety of laser diode drivers designed for high power and precision applications for Quasi-CW (QCW) and Continuous Wave (CW) operation.

High compliance voltages allow for both single diode and diode array use as well as non-laser applications requiring a current source.

These instruments are perfect for research & development, materials processing, characterization, and testing of laser diodes. We offer instruments, standard modules and OEM modules tailored through our Lab to Launch program.

Typical Applications

LIDAR
Marking and Engraving
Scientific Research
Micromachining
Medical & Cosmetic Laser

Laser Diode Driver Short-form Catalog

Our Laser Diode Drivers are sorted by Compliance Voltage by default but you can sort any column by clicking the column header or search by part number or parameter in the search field on the right.

Filter by Compliance Voltage (V), Maximum Current (A), Maximum Frequency (kHz), Minimum Pulse Width (PWm), Computer Control and Form Factor with the filter selection tool.

* The specifications listed below represent the highest performance point. Consult the datasheet and/or operating manual to see full safe operating area (SOA) information.
