Abstract

This utility model relates to the field of laser technology, specifically providing a laser pulse width calibration device. It includes a calibration circuit board, a seed laser, a photoelectric sensor, and a processor. The output terminal of the calibration circuit board is electrically connected to the input terminal of the seed laser, used to transmit an electrical trigger signal corresponding to the pulse width to the seed laser. The output terminal of the seed laser is connected to the input terminal of the photoelectric sensor, used to output an optical pulse signal corresponding to the pulse width. In the photoelectric sensor, a photoelectric converter converts the optical pulse signal output by the seed laser into a voltage signal. The input terminal of a multi-stage amplifier circuit is electrically connected to the output terminal of the photoelectric converter, used to amplify the voltage signal output by the photoelectric converter. The first input terminal of the processor is electrically connected to the output terminal of the photoelectric sensor, and the processor is used to check whether the bandwidth of the optical pulse signal meets the standard. This achieves automatic pulse width calibration, effectively improving calibration efficiency and stability.
