PROBLEM TO BE SOLVED: To eliminate the troublesome adjustment of an optical axis compared to a former case and to reduce the cost of a laser oscillator. SOLUTION: A laser oscillator 1 is provided with first solid state laser mediums 4 and second solid state laser mediums 5 which are oppositely arranged and reflect laser beams L zigzag and a reflecting mirror 7, and an output mirror 8 which face to the laser beam. The plural first solid state laser mediums 4 are installed on a first substrate 2 by leaving intervals. The plural second solid state laser mediums 5 are installed on a second substrate 3 by leaving the intervals. Introduction ports 12 and 13 introducing exciting laser beams are installed in a resonator space between the first solid state laser mediums 4 and the second solid state laser mediums 5. |
