Applications

Laser Diodes

Solid state lasers are widely used as an important sources of laser output at specific wavelengths in visible ,infrared and ultraviolet band, the combination of wide optical transmission and high Raman gain of CVD diamond can benefit the design and performance of the laser. CVD diamond has higher thermal conductivity , low thermal expansion coefficient and damage resistance and can be used to develop lasers with stronger output power, compactness and variable wave length

Microwave Window

Diamond is the key window element of gyrotron and microwave wave guide in magnectically confined nuclear fusion reactor . Diamond microwave windows can withstand continuous high power density energy of more than 2MW are used in satellite, Aerospace and defense industry.

Infrared Window

Infrared window is and important structure and functional compoment in military , with its excellent transmittance ,high thermal conductivity , estradoniary hardness and chemical and wear resitance,low scattering coefficient,CVD diamond infrared window is widely used in the military equipment
