20mW Lasers

What are 20mW Lasers?

20mW lasers can be any device that emits or that specifically designates 20mW (0.02W) of average output power 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.
