0.75mW Lasers

What are 0.75mW Lasers?

Lasers that designate 0.75mW of output power (also called 0.00075W 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.

Our HeNe lasers provide low output powers in the milliwatt (mW) range. 0.75mW HeNe lasers are available in HeNe laser module and HeNe laser tube configurations. Low power HeNe lasers can be utilized for applications like interferometry for example.
