Abstract : In the patent, scanning of a high power laser beam while it is being used is accomplished by deflecting the laser beam to its target with a polished metal mirror. Multiple thermocouple wires attached to the rear of the mirror provide temperature (and hence beam power) information at various points on the mirror. Scanning is achieved by means of a selector switch which sequentially samples the thermocouple outputs. The thermocouple output voltages are measured and recorded as a function of laser beam power.
