摘要

摘要: 针对现有激光器多光路加工特点,采用Nd: YAG脉冲激光器为光源,研制出激光器双光路输出分时控制系统。提出了具体的分时分光技术方案,设计出能够实现分时分光的分光装置,以及对装置的工作状态进行实时控制的分时控制电路,并确定了系统的程序流程。在不降低输出功率的前提下,实现了激光在不同时间、不同输出端口的输出,完成了分时分光。为避免因分光装置抖动而造成的光纤损坏,利用黑色相纸对光斑进行采样。结果表明:在全反镜改变位置后至激光输出,延时300 ms为最佳时间。该系统能实现激光的时分复用、动态分光,满足了多光路输出需求;而且系统的扩展能力强,能够根据实际激光加工状况,为激光加工设备的改进和升级提供思路。

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.
