Study on parameters measurement technology of high energy and high power laser

The current situation and measurement requirements of high energy and high power laser technology were briefly described. The progress of parameters measurement research for high energy and high power laser in recent years was introduced, and the measurement principle and method of laser power energy, time-domain parameter and space-domain was given. The main problems of high energy and high power laser parameter measurement and the key technologies to be broken through are pointed out, including large dynamic range power energy “distortion-free” attenuation technology, laser power energy field measurement technology, power energy meter traceability and backscatter compensation method, etc.
