摘要
介绍了光纤传输脉冲固体激光切割机系统的设计原理及工作特点,主要是优化设计光纤传输系统,使光纤输出后的激光束聚焦光斑直径尽量小;满足激光切割所需功率密度要求。系统使用双灯单棒的聚光腔,光纤输出后的功率达到400W,最小光斑直径小于0.25mm,可满足1~4mm内的碳钢、不锈钢等金属材料的切割要求。该系统可配合数控工作台、机器人或手持使用,为钣金行业提供了一种较好的激光切割方案。
Introduce the designing theory and working characteristic of Fiber delivery pulsed solid state laser cutting system.The fiber delivery system was improved and achieved the smaller spot size after focusing.The system is adopted with double lamps one crystal pumping chamber.Fiber delivery output up to 400W,minimum spot size is 0.25mm.And it call fulfill 1-4mm metal cutting requirement,such as carbon steel,S.steel and etc.As a good solution for Sheet metal industrial,it can integrate with CNC table,robotic or joystick.
