Abstract
A compact and inexpensive laser apparatus capable of obtaining laser beams of multiple wavelengths from a single solid crystal 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.
Claims4
A laser apparatus comprising an excitation light source unit for exciting a laser medium to generate a laser beam, a resonance unit for resonating the laser beam generated by the light source unit, and a harmonic element for modulating the wavelength of the laser beam,
- the laser apparatus being enabled to carry out multi-wavelength laser oscillation at the same time by forming the laser medium of a solid crystal of a Raman effect substance or forming the laser medium of a solid crystal of a non-Raman effect substance and providing the resonance unit with a solid crystal of a Raman effect substance, wherein:
- a single wavelength is selectively extracted out of multiple wavelengths by adjusting the angle of the harmonic element relative to the optical axis.
