High-power and high-energy laser systems have various industrial applications. Again, the exit window becomes the limiting factor to what is the maximum power can be extracted and also need to change frequently with degradation over time and uses. With its superior thermo-mechanical properties, our CVD diamond outperforms the conventional ZnSe windows and optical components for multi-kilowatt CO2 lasers at 10.6 micron and also as heat-spreaders, output couplers and active components.
Optical lens applications require low spherical aberration and a low absorption coefficient and high thermal conductivity to avoid a distortion of the transmitted wave front due to thermal lensing. CVD-diamond lenses are used for various optical lens applications in high-power CO2 lasers.
