Abstract
The copper HyBrID laser is a significant new variant of the traditional copper vapour laser (CVL) which is capable of generating high average power (>200W [1]) at elevated pulse repetition frequencies (~17kHz) with electrical efficiencies 2-3x higher than conventional CVLs (ie 2-3%). While the raw power performance of these devices is relatively well characterised, there has been little attention paid thus far to the issue of high beam quality operation of these devices, which is critical for emerging CVL applications such as micromachining and nonlinear frequency conversion.
