Abstract
A semiconductor laser device includes first heat radiator () having first flow path () and second flow path () inside to allow a flow of a refrigerant and second heat radiator () put in contact with an upper surface of the first heat radiator. The first flow path and the second flow path are independent of each other. The second heat radiator includes an insulating member that internally has third flow path () communicating with first flow path (). The semiconductor laser device further includes lower electrode block () disposed on a portion of an upper surface of the second heat radiator, submount () being made of a conductive material and being disposed on a remainder of the upper surface of second heat radiator (), semiconductor laser element () disposed on an upper surface of submount (), and upper electrode block () disposed such that submount () and semiconductor laser element () are clamped between the upper electrode block and second heat radiator (). Second flow path () is formed below a zone for the disposition of lower electrode block ().
