Because a laser device is constructed in such a way that the laser device includes a solid-state laser element 3 that has gains for plural different wavelengths in plural different axial directions, and an optical element that has a characteristic of making an optical loss increase with increase in light intensity for each of light beams with the wavelengths, and the solid-state laser element 3 and the optical element are constructed in such a way as to be included in a resonator for fundamental waves which are generated by the solid-state laser element 3, and the laser device oscillates at two or more wavelengths, outputted light beams with the plural different wavelengths can be acquired by using the single solid-state laser element 3. As a result, a small, cheap, and easy to produce laser device can be acquired. |
