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