Title: LASER AMPLIFYING MEDIUM, LASER OSCILLATOR, AND LASER AMPLIFIER
Abstract:
A laser amplifying medium according to the present embodiment includes a solid-state laser medium and a pair of reflectors, and can be applied to a side-pumped laser oscillator or the like. The solid-state laser medium has a refractive index within the range of 1.7 through 1.9 with respect to excitation light or the like, and has a bottom face substantially formed into a parallelogram with one inner angle forming an acute angle within the range of 58 through 62 degrees. One of the surfaces forming the acute angle is disposed in an amplification optical path while excitation light is incident on the other surface. The pair of reflectors is disposed on a portion of the surface whereon the excitation light is incident and on a surface opposite thereto, thereby serving to deflect the excitation light that propagates through the solid-state laser medium in the traveling direction.
