Element Six

Element Six will showcase its Optical+ Low Absorption diamond, which can be used as a gain medium for Raman lasers and as a low loss intra-cavity heat spreader for high power disk lasers. Raman crystals are offered in sizes up to 6 x 6 x 2mm, with larger sizes available on request. 

Also featured will be the company’s Diamond PureOptics range. Drawing inspiration from the anti-reflective structure of a moth’s eye, this all-diamond solution offers improved reliability and even higher power density levels for high power CO2 laser systems. Element Six have replaced the typical anti-reflective thin film coatings found on diamond optical windows with a diamond structured surface designed to reduce reflection losses. Diamond PureOptics exhibits significantly higher laser induced damage threshold (by a factor of 10) than anti-reflective coated windows, with equivalent reflectance (less than 0.5 per cent) and transmission (above 99 per cent).
