Abstract
A solid laser produces a laser beam of a 1 &mgr;m wavelength band with an Nd-doped solid laser medium. An oscillation mode is brought to a single longitudinal mode with a Fabry-Pérot etalon located within a resonator. An etalon thickness, an etalon reflectivity, an etalon inclination, and a resonator longitudinal mode interval satisfy the relationships, 1.2%≦R ≦15% and 0.5°≦&thgr;≦2.0°, in which R represents an effective reflectivity of the etalon with respect to wavelengths &lgr;=&lgr; ±&Dgr;&lgr;c deviating by a resonator longitudinal mode interval &Dgr;&lgr;c from a resonance wavelength &lgr; of the etalon, and &thgr; represents an inclination of an etalon optical axis with respect to a resonator optical axis.
