Synthetic diamond, deposited by Chemical Vapour Deposition (CVD), is becoming an interesting alternative for ZnSe as a window material for high power CO lasers. Although the infrared absorption of CVD-dianiond is higher than of ZnSe, this drawback is

We report on the characterisation of the refractive index homogeneity in large blanks of Czochralski-grown Germanium, for thermal imaging use. With a phase-measuring Twyman-Green interferometer working at 10.6 mu m, a map of the index of refraction w

We report on the characterization of infrared materials using a phase measuring Twyman Green interferometer at 10.6 micron. Parameters studied are refractive index, wavefront distortion and optical homogeneity. The materials which were considered are

In CO2 laser engineering, combining high output power with low distortion of the laser beam is an ongoing challenge, leading to a search for optics with low absorption and high thermal conductivity. As CVD diamond has recently become available in lar

In CO2-laser engineering, combining high output power with a good laser beam quality is a very challenging design problem. Due to residual absorption in the output coupler (O.C.), thermal aberrations are added to the transmitted beam which result in
