Abstract

On account of the characteristics of laser double-pass processing,a Nd∶ YAG pulsed laser is chosen as the light source,and a laser time-sharing control system for double-pass outputs is developed.A concrete implemented project for time-sharing spectral technology is put forward,the beam split device is designed to achieve time-sharing beam split,and the time-sharing control circuit is designed to control the device in real time.Then,system program procedure is determined.Finally,laser outputs from different ports in different time are obtained under keeping the output powers.In order to avoid fiber damaging because of the jittering from beam split device,black photographic paper is used to sample of facula.The result shows that the best delay time is 300 ms from changing the holophote position to laser output.This system can not only realize time-share multiplexing and dynamic spectral splitting,but also can satisfy the need of double-pass outputs.Furthermore,the system has a stronger expanding ability,and can provide the convenience for laser improvement and upgrade according to the laser processing condition in reality.
