The rapid inspection method of an O-E receiver

摘要

For the first time, the rapid inspection method of an O-E receiver based on second-harmonic is proposed for measuring 1.064 micrometers and 0.91 micrometers laser pulse with duration of about 10nm. By comparing the two waveforms from a pulse of laser, we achieve more than 0.6% relative error of pulse-width. The opto- electronic receive have inspected come into use for measuring laser waveform. The measurement uncertainties of ratio of integration area to peak voltage of the laser waveform is 0.6%. It is shown that the ratio is an important parameter for evaluating the accuracy of laser waveform, in contrast, the transient time invariance and linearity of opto-electronic detector is verified.
