Abstract
A laser pulse sampling and detecting circuit includes: a laser driver which is driven by a triggering signal for generating laser pulse signal; a photoelectric converter for converting the laser pulse signal into current pulse signal; an amplifier for amplifying and converting the current pulse signal into voltage pulse signal; an ADC which is driven by a sampling clock signal for sampling the voltage pulse signal and performing analog-to-digital conversion on the voltage pulse signal, so as to obtain output signal of the ADC; a detector for detecting the output signal of the ADC, so as to obtain peak power and FWHM of the laser pulse signal; and a clock generator for generating the sampling clock signal. Phase of the sampling clock signal consecutively changes with respect to the triggering signal.
