<p>A compact laser apparatus (1) capable of obtaining laser beams of multiple wavelengths from a single solid crystal (10) at the same time and excelling in reliability and efficiency is to be provided. A laser apparatus (1) uses a solid crystal consisting of a Raman effect substance as a laser medium (10), and is equipped with a laser oscillator (12) for exciting the laser medium (10) to generate laser beams, a reflector (16), a laser output mirror (18), for resonating the laser beam generated from the laser medium (10) and a harmonic element (22) for enabling by angle adjustment a single wavelength to be extracted out of multiple oscillation wavelengths. In an alternative embodiment the laser medium (10) is formed of a solid crystal having no Raman effect, and a separate solid crystal (11) of a Raman effect substance is provided in the resonator.</p> |
