Diamond–silicon carbide composite “skeleton” as a promising heatsink material for Yb:YAG thin-disk lasers

It is proposed to use a new diamond–silicon carbide (DSC) composite “skeleton” as a heatsink material for Yb:YAG thin-disk lasers. The main advantage of the DSC “skeleton” over a conventional diamond is a possibility to manufacture parts of almost any size and shape, which allows optimizing heat removal parameters and achieving better mechanical and thermophysical properties. Temperature distribution, phase distortions, and lasing in the active elements on heatsinks made of DSK “skeleton” and diamond are compared theoretically and experimentally.
