Development of high quality single crystal diamond for novel laser applications

The extreme properties of diamond make it an exceptional material for a range of demanding optical applications. However, the use of single crystal diamond in lasers has been limited by the availability of suitably-sized crystals with low absorption, and the relatively high levels of strain-related birefringence present. We present recent progress in CVD diamond synthesis which addresses these properties, and show how this new high quality, engineered diamond is enabling novel laser technologies such as mid-IR semiconductor disk lasers and high efficiency diamond Raman lasers.
