PROBLEM TO BE SOLVED: To permit the manufacture of a miniaturized and inexpensive laser oscillation device, high in the output thereof compared with a conventional device, and oscillating a plurality of kinds of laser beams, since a plurality of dope units 3, 4 are provided in one non-dope unit 2. SOLUTION: The laser oscillation device is provided with a laser crystal 1 equipped with a plurality of dope units 3, 4 in the non-dope unit 2 while the plurality of dope units 3, 4 are arranged in one set of resonator optical path 11. In another way, a plurality of resonator optical paths are provided and at least one dope unit is arranged in each resonator optical path. These dope units can be units for exciting laser beams of the same wavelength or can be units for exciting at least two kinds of laser beams having wavelengths different from each other.
