Abstract:
A mounting structure comprising:a semiconductor laser module; a mounting substrate for mounting the semiconductor laser module; and a thermal diffusion sheet member disposed between the semiconductor laser module and the mounting substrate: wherein the semiconductor laser module comprises a semiconductor laser chip mounted on a chip mounting substrate, a thermo-module configured to cool the semiconductor laser chip, and a package having a bottom plate and housing the semiconductor laser chip and the thermo-module, the thermo-module being interposed between the bottom plate of the package and the chip mounting substrate; and wherein the thermal diffusion sheet member is disposed between the bottom plate of the package and a surface of the mounting substrate, the thermal diffusion sheet member having an anisotropic thermal conductivity such that the thermal conductivity along a direction in a sheet surface is higher than along a thickness direction; and, wherein the semiconductor laser module, the thermal diffusion sheet member and, the mounting substrate are in thermal communication with each other.
