SOLID LASER EXCITATION MODULE

摘要

A solid laser excitation module (1) comprising a flat additive-free medium (4) that is provided on the surface side opposite to the reflection surface of a thin solid laser medium (3), and is close in refractive index to the medium (3) and free from an active medium, wherein an excitation light is reflected off the reflection surface of the medium (3) and the reflection surface, on the surface side opposite to the medium (3), of the additive-free medium (4) to excite the thin solid laser medium (3) and allow a laser beam to be extracted.
