Detection Methods of Far-field Energy Density of the High Power Pulse Laser
高功率脉冲激光的远场能量密度分布测试方法研究

The detection mehtods of far-field laser energy density distribution was analyed,and a new detection method was proposed.Using laser beam shoot to the reflex tartget board,taken image of the laser spot on the board by CCD camera and surveyed the sampling energy value by energy detector which lies on the board,the laser beam propagating through amosphere far-field distribution was obtained.The basic module and the detection principle etc.of new detection method was analysed,and verified In experiment,532 nm pulse laser shoot to the reflex tartget board,the laser far-field spot image and the sampling energy value was gained.
