Development of measuring parameters system for high-power laser

The method of measuring accurately energy and pulse time waveform of laser was studied in ICF experiment. A beam was introduced to the energy meter through attenuator. Analog signal from amplifier of the energy meter was input into 8098 single-chip processor after normalized and A/D converted. Data acquired was transferred to master console through the beam coupling communication network and the interface circuit. Another laser beam was changed into electric pulse by ultra-fast photodetectors and input the oscilloscope. Data acquired by the oscilloscope was transported to master console through GPIB bus and GPIB-LAN adapter AD007 by means of VISA language. Waveform parameters were extracted from pulse waveform data which was filtered by wavelet transform through self-adaptive algorithm.
