Solid-state laser device and photoacoustic measurement device

A solid-state laser device comprising:

• a laser chamber which has an internal space;
• a solid-state laser medium, at least a part of which is accommodated in the laser chamber;
• an excitation light source which has a rod-shaped portion extending linearly, a part of the rod-shaped portion being provided inside the laser chamber as a portion emitting excitation light exciting the solid-state laser medium, and both end portions being provided outside the laser chamber;
• and
• a pair of resonator mirrors which resonate light emitted from both end portions of the excited solid-state laser medium,
• wherein the rod-shaped portion of the excitation light source is provided to be moved in a longitudinal direction of the rod-shaped portion and capable of being pulled out of the laser chamber,
• an optical element which bends light emitted from one end surface of the solid-state laser medium in a transverse direction is provided to face the one end surface of the solid-state laser medium,
• the optical element is provided at a position separated from the rod-shaped portion such that at least a part of the optical element and at least a part of the rod-shaped portion are at the same position in the longitudinal direction of the rod-shaped portion,
• one of the pair of resonator mirrors is disposed at a position where light bent by the optical element is incident, and
• optical components between the optical element and the one resonator mirror are provided at positions separated from a path along which the rod-shaped portion of the excitation light source is pulled out.
