PURPOSE:To stably emit a laser beam even if the ambient temperature changes, by using a semiconductor lasers of a plurality of wavelengths one of which is within the absorption band of a solid laser material at the working temperature. CONSTITUTION:A solid laser device which performs excitation with semiconductor lasers is made to emit a laser beam having a plurality of wavelengths 140a and 140b of the semiconductor lasers and one of them is within the absorption band of a solid laser material 100 at the working temperature. This enables stably emitting a laser beam without using a complicated temperature controller even if the ambient temperature changes. |
