Frequency conversion device for forming semiconductor laser device, has electric thermal resistor applied on upper surface of electric insulation support and provided between support and frequency conversion crystal

摘要

The device has a heating element provided for a frequency conversion crystal (7) and including an electric insulation support (1) that consists of a material, which possesses thermal conductivity of 3 watt/meter Kelvin or glass. An electric thermal resistor (2) is applied on an upper surface (5) of the support, and is provided between the support and the frequency conversion crystal. The support is provided with a recess at the upper surface, where the support has thickness of 200 micrometers and 400 micrometers at a region of the recess. An independent claim is also included for a method for producing a frequency conversion device.
