LASER OUTPUT MEASUREMENT MECHANISM |
摘要 |
A laser output measurement mechanism includes a light splitter that is disposed in a state rotated by a predetermined angle about an optical axis of laser light incident thereon, and that reflects a part of the laser light according to a Fresnel reflectivity that depends on a polarization direction and an incident angle of the laser light at a reflection surface thereof, and a light detector that measures an intensity of the laser light reflected by the light splitter. |
