Solid laser excitation module

摘要

A solid state laser pumping module ( 1 ) is so constructed as to have a plate-shaped non-doped medium ( 4 ) having a refractive index close to that of a thin solid state laser medium ( 3 ) and having no active material, the non-doped medium being disposed on a surface of the thin solid state laser medium ( 3 ) which is opposite to a reflecting surface of the thin solid state laser medium ( 3 ). Pumping light is reflected between the reflecting surface of the thin solid state laser medium ( 3 ) and a reflecting surface of the non-doped medium ( 4 ) arranged on a side of the opposite surface of the thin solid state laser medium ( 3 ) while pumping the thin solid state laser medium ( 3 ). A laser beam is taken out of the thin solid state laser medium.
