Lasers designating 0.5mW of output power (also called 0.0005W 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.
0.5mW lasers are very low power lasers. Depending on the wavelength, lasers that have a low output power level in this range can be good for various applications such as confocal fluorescence microscopy, holography, interferometry, non-linear spectroscopy, optogenetics, particle measurement, and for RGB light sources.
