Laser-diode-pumped solid state laser and an optical system using the same

摘要

A laser-diode-pumped solid state laser comprises: a solid laser medium; a laser-diode capable of producing a laser beam for exciting the solid laser medium; a pair of mirrors which forms a resonator for resonating a light excited by the solid laser medium. An interval between the pair of mirrors is determined such that a gain width GW of the solid laser medium and a frequency interval FS (between every two resonator modes) satisfies an equation 0.1≦FS/GW1.
