The utility model discloses a laser device. The laser device comprises a plurality of LD pump sources, a laser crystal, a frequency doubling crystal and a light combining prism. The plurality of LD pump sources are used for emitting multiple pump light beams. The laser crystal is used for converting the multiple pump light beams into multiple fundamental frequency light beams. The frequency doubling crystal is used for converting the multiple fundamental frequency light beams into multiple frequency doubling light beams. The light combining prism is used for combining the multiple frequency doubling light beams into a laser beam. The light combining prism is formed by gluing inclined surfaces of a plurality of rhombic prisms and the inclined surface of a right-angle prism together, wherein the inclined surface of each rhombic prism is used to reflect the laser beam which is incident onto the rhombic prism from a corresponding light incident surface thereof to the next inclined surface, and the right-angle pri
