300mW Lasers

What are 300mW Lasers?

Lasers that designate 300mW (0.3W) of output power can have either continuous-wave (CW) 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.
