CVD diamond is considered to be an ideal heat spreading material suitable for high 
power electronic and optoelectronic devices. Applications include laser diodes and diode 
arrays used in optical fiber communications and as optical pumps for high power solid 
state lasers, high power microwave devices for radar and high density multi-chip.   Additionally,CVD diamond can be produced in shapes and sizes. And the mechanical properties of CVD diamond share some advantages of both single crystal diamond and PCD.
  The thick film-supported CVD diamond material can be used in machine cutters, diamond dressers, diamond wire drawing die blanks, electronic components heat spreaders and other fields.

0.3-3 mm thick, the max diameter is 200 mm 

The skills of diamond film growing technology developed by GH, lapping , polishing, laser cutting and own many patents in The thick film-supported CVD diamond material producing and processing field.
