CW and Quasi-CW Laser Diode Drivers

CW & 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
  • Marking and Engraving
  • Scientific Research
  • Micromachining
  • Medical & Cosmetic Laser

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.
