Abstract
A solid-state laser device includes a resonator composed of a pair of mirrors; a laser rod disposed in the resonator, the laser rod including an antireflection film on an end surface thereof and having a chamfered portion at a peripheral edge of the end surface; and an end-surface protection member that is disposed at a position facing the end surface of the laser rod, that has an opening defining portion that forms an opening whose diameter is smaller than a diameter of an outer periphery of the end surface, and that limits a laser light path region in the end surface of the laser rod to a region inside of the outer periphery of the end surface.
