Lasers that designate 900mW of 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.
The LaserBoxx HPE series is a high power laser diode module offering excellent performance and reliability in a compact driver integrated laser head (Industry-standard compact package). It comes in free space multimode elliptical beam or with removable MM fiber coupling.
