光斑整形　Laser Beam Shaper

與傳統(tǒng)透射型的光束整形方式相比，NTTAT反射式光束整形技術(shù)，增大了光學(xué)器件的冷卻面積，在高功率光束整形時，整形器件良好的熱處理能力使光束整形后的輸出更加穩(wěn)定。

在NTTAT實驗室測試記錄中，最高光束整形激光功率可高達10000瓦。除此外，NTTAT反射式光束整形技術(shù)還能實現(xiàn)多焦點光束整形。

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，因為冷卻面積小，冷卻效率低，光束整形后輸出逐漸變形扭曲；

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

l NTTAT反射式光束整形技術(shù)，因為在器件背部有大的冷卻面積，冷卻效率高，光束整形輸出后始終如一的穩(wěn)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.

經(jīng)過光束整形之后，高斯光斑可變成方形平頂、矩形平頂、圓形平頂、橢圓形平頂、線形、環(huán)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.
