PURPOSE:To generate a laser beam, which is stable, has a high output and is good in quality, at a high efficiency by a low-cost constitution. CONSTITUTION:A solid-state element 3 containing an active solid medium is arranged in a condenser 8, whose inner surface is constituted of a light diffusion reflective surface, an excitation light source 4 is installed outside of the condenser 8, excitation light 40 is introduced in the condenser 8 through an opening part 80 opened in the condenser 8, the element 3 is light-excited from the side surface of the condenser 8 and a laser beam 70 is taken out by a laser resonator constituted of mirrors 1 and 2. In such a way, a light excitation solid-state laser is constituted. |
