4mW Lasers

What are 4mW Lasers?

Lasers that designate 4mW of output power (also called 0.004W lasers) can have either CW (continuous wave) or pulsed output. CW Lasers are always defined in average output power. Pulsed Lasers with an output power defined in Watts or Milliwatts usually define the laser’s average power, not the peak power of the laser.

RPMC currently offers a couple configurations of compact, rugged, lightweight, microchip lasers (micro lasers), emitting an average output power of 4mW.
