摘要
Abstract
A peak value hold circuit is developed for the energy measurement of a high-repetition-rate pulsed laser.The circuit consisting of four modules including a charge integrator,a 2nd-order Butterworth low-pass filter,a time-delay trigger and a peak-value-holder is designed to convert the photocurrent pulses to voltage pulses which are linear to the energies of incident pulse laser.The experimental measurement results indicate that this circuit is suitable for the pulsed laser with a width less than 10 ns and a repetition rate over 2 kHz.The results show that the circuit has a dynamic range about 140 times and works stably.It can be used to achieve a high spatial resolution in photodiode measurement systems.关键词
