日本NTTAT产品 - 光斑整形


光斑整形 Laser Beam Shaper



与传统透射型的光束整形方式相比,NTTAT反射式光束整形技术,增大了光学器件的冷却面积,在高功率光束整形时,整形器件良好的热处理能力使光束整形后的输出更加稳定。

在NTTAT实验室测试记录中,最高光束整形激光功率可高达10000瓦。除此外,NTTAT反射式光束整形技术还能实现多焦点光束整形。

Compared with the transmission-type beam shaper, NTTAT reflection-type beam shaper increases the cooling area of optical devices. When high-power beam shaping, the good heat treatment ability of beam shaper makes the output beam more stable.

In the NTTAT laboratory test record, the maximum beam shaping laser power can be up to 10000 watts. In addition, NTTAT reflection-type beam shaper can realize multi focus beam.

l 透射型光束整形,因为冷却面积小,冷却效率低,光束整形后输出逐渐变形扭曲;

   Transmission-type beam shaper, small cooling area, low cooling efficiency, the output of beam shaper is gradually distorted.


l NTTAT反射式光束整形技术,因为在器件背部有大的冷却面积,冷却效率高,光束整形输出后始终如一的稳定。

   NTTAT reflection-type beam shaper, large cooling area at the back of the shaper, high cooling efficiency, the output of beam shaping is always stable.

经过光束整形之后,高斯光斑可变成方形平顶、矩形平顶、圆形平顶、椭圆形平顶、线形、环形等光斑。

After beam shaping, Gaussian facula can be transformed into square flat top, rectangular flat top, circular flat top, elliptical flat top, linear, circular and other facula.
