What are the applications of picosecond laser cutting machines?

发布人:莱塞激光 发布时间:2021-06-30 16:39:35

【摘要】

Picosecond laser cutting machine is mainly composed of picosecond laser, light guide, focusing system, displacement platform, computer control system and other auxiliary systems. Picosecond laser is a high peak value ultra-short pulse laser. Its principle is that the laser beam is focused and irradiated on the workpiece, and then it is instantly

皮秒激光切割机主要由皮秒激光、光导、聚焦系统、位移平台、计算机控制系统和其它辅助系统组成。皮秒激光是高峰值的超短脉冲激光。其原理是,激光束聚焦后照射到工件上,瞬时高能加热材料,使之熔化或蒸发。

它的优点有很多种,主要有以下几点:

1、真冷加工,基本不碳化;

2、超短脉冲,能量在皮秒级释放,热影响区小,可忽略,无微裂纹;

3、速度快,皮秒重复频率非常高,振镜速度快;

4、切割效果精细,皮秒加工采用小单脉冲能量,高频加工,加工面更精细;

5、加工材料较多,适合各种材料加工。
