ABSTRACT:
Apparatus for measuring power in a laser-beam includes a transmissive diffuser for diffusely expanding the laser-beam and a photon detector for receiving the diffusely-expanded laser-beam and generating an electrical signal in response thereto. Electronic circuitry including a microprocessor is provided for interpreting the electrical signal as a measure of power in the laser-beam. A display device is provided for displaying the interpreted signal.
