PROBLEM TO BE SOLVED: To provide a small-sized inexpensive laser apparatus obtaining laser beams of multiple wavelengths from a single solid crystal at the same time and having high reliability and oscillation efficiency. SOLUTION: There is formed a laser apparatus 1 provided with: a laser oscillator 12 using a Raman crystal for a solid crystal of a laser medium 10 and exciting the laser medium 10 to generate laser beams; a reflecting mirror 16 and a laser output mirror 18 resonating the laser beams generated from the laser medium 10; and a harmonic element 22 selectively extracting a single wavelength from multiple wavelengths oscillating a visible region by angular adjustment.
