Abstract
Two laser media are disposed at equal intervals between a first flat mirror, which is a resonator mirror comprising a resonator, and a second flat mirror for separating laser light that transmits second-harmonic laser light and reflects fundamental laser light toward a laser light incident plane; and a dielectric multilayer film is formed on the second flat mirror for separating the laser light. A third flat mirror, which is a resonator mirror, is disposed so as to face a direction 90° to the incident direction of the fundamental laser light in the second flat mirror. A first lens, a nonlinear optical crystal for converting fundamental laser light into a second-harmonic laser light, and a second lens are disposed in sequence in a single row at intervals that are equal to the focal distances f of the first and second lenses between the second and third flat mirrors. Space for accommodating a nonlinear optical crystal and a mirror for separating second-harmonic laser light can thereby be secured while maintaining stabilized resonance conditions, and the output of the solid-state laser generator can be increased.
