PROBLEM TO BE SOLVED: To provide a solid-state laser device which can excite a laser rod formed of a solid-state laser medium uniformly and efficiently with a simplified constitution. SOLUTION: The solid-state laser device is so structured that excitation lights emitted from laser diodes 11a, 11b, and 11c may be introduced into a flow tube 15 in an expanded condition due to optical action of sectorial lenses 12a, 12b, and 12c after being passed through slits 17a, 17b, and 17c, and that part of each excitation light may be irradiated head-on upon the laser rod 13. Remainder of each excitation light is passed through the flow tube space without being irradiated on the laser rod 13 and is reflected on reflective coating portions 16a, 16b, and 16c formed on the outer peripheral surface of the flow tube 15 to be irradiated on the laser rod 13 from a non-frontal direction.
