The Rapid Inspection Method Of An O-E Receiver

For the first time, the rapid inspection method of an O-E receiver based on second-harmonic is proposed for measuring 1.064 mum and 0.91 mum laser pulse with duration of about 10ns. By comparing the two waveforms from a pulse of laser, we achieve mom 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.
