Abstract:
A solid state laser device comprising:a laser semiconductor for oscillating a laser light as a pumping light, a collimator lens for leading the laser light to parallel rays, a focusing lens for focusing the laser light led to the parallel rays by the collimator lens and leading the focused laser light to a laser medium, the laser medium for absorbing the laser light and outputting a spontaneous emission light, and an optical resonator for confining the spontaneous emission light to make the laser light oscillated by an induced emission, wherein the solid state laser device includes a first housing for storing the laser semiconductor and the collimator lens in a state of positioning them on the same optical axis, and a second housing for storing the focusing lens, the laser medium and the optical resonator in a state of positioning them on the same optical axis, and the housings are detachable.
