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.
A solid state laser pumping module including a plate-shaped thin solid state laser medium, a reflecting means formed on a plane surface of said thin solid state laser medium, a cooling means bonded to said reflecting means, a pumping source for providing pumping light to said thin solid state laser medium, laser light being incident upon a laser light incidence surface which is opposite to said reflecting means, characterized in that said thin solid state laser medium is a plate whose at least a part on a side of said reflecting means has an active material doped thereinto, a plate-shaped non-doped medium is disposed on another plane surface of said thin solid state laser medium which is opposite to said plane surface of said thin solid state laser medium on which said reflecting means is disposed, and said two plates are optically bonded to each other.
