SOLID-STATE LASER APPARATUS AND PHOTOACOUSTIC MEASUREMENT APPARATUS

摘要

PROBLEM TO BE SOLVED: To achieve simplification and miniaturization of constitution in a solid-state laser apparatus capable of extracting an excitation light source from a laser chamber.SOLUTION: In a solid-state laser apparatus 10 accommodating a solid-state laser medium 12 and an excitation light source 13 having a rod-like portion, the excitation light source 13 is arranged so as to be moved in a longitudinal direction and extracted from a laser chamber 11. An optical element 21 for bending light generated from the solid-state laser medium 12 in a lateral direction is prepared and arranged on a position where at least a part of the optical element 21 is arranged on the same position as the rod-like portion in the longitudinal direction of the rod-like portion and the optical element 21 is separated from the rod-like portion. One resonator mirror 23 is arranged on a position on which bent light is made incident. Optical elements from the optical element 21 up to the resonator mirror 23 are arranged on positions separated from an extraction locus of the excitation light source 13. Further, the solid-state laser apparatus 10 is applied to a photoacoustic measurement apparatus 100.
