一、原理和结构高重复率脉冲激光能量监测装置是根据图1所示的原理制成的.硅光二极管D受脉冲激光照射后产生脉冲的光电流,对电容器C充电,电容器两端电压V和电量Q有如下关系:Q=CV(Q对应于激光的能量E),即有Q=kE,k是硅光二极管光电转换常数.然后,电容器上的电量通过RC放电,放电曲线的面积就代表激光能量,这就把测量激 First, the principle and structure of high repetition rate pulsed laser energy monitoring device is based on the principle shown in Figure 1. Silicon photodiode D pulsed laser pulses generated by the photocurrent, the capacitor C charge, the voltage across the capacitor V And the power Q have the following relationship: Q = CV (Q corresponds to the laser energy E), that is, Q = kE, k is the silicon photodiode conversion constant, and then the capacitor discharge through the RC, discharge curve area On behalf of the laser energy, which put the measurement shock
