Element Six will showcase its Optical+ low absorption diamond at the show, which can be used as a low loss intra-cavity heat spreader for high power disk lasers, as well as a gain medium for Raman 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).
The Tm200 is the highest thermal conductivity bulk heat spreader material on the market: room temperature thermal conductivity >2,000W/mK, for greater reliability and reduced system size in optoelectronic high power and high power density devices.
