Solid-state laser device

A solid-state laser device comprising:

• a linear resonator in which an output mirror and a rear mirror are disposed on a straight line;
• a laser rod disposed on an optical path of the resonator;
• optical members at least including a Q-switch;
• and
• a rod-shaped excitation light source that extends parallel to the laser rod and emits excitation light that excites the laser rod,
• wherein the resonator, the laser rod, and the optical members are provided on a common base and are contained in a housing having the base as a portion,
• wherein a holding part is provided to hold the excitation light source parallel to the laser rod on a side of the laser rod opposite to the base,
• wherein the optical members including the Q-switch are disposed between the laser rod and the rear mirror,
• wherein an upper end position of the output mirror is at a position lower than a lower end position of the excitation light source held by the holding part, with the base as a reference, and
• wherein the holding part holds the excitation light source so as to be capable of being inserted and extracted with respect to the output mirror side in a longitudinal direction of the excitation light source.
