Abstract
Copper vapor lasers (CVLs) are increasingly being used for applications such as pumping Ti. sapphire lasers1 and nonlinear second-harmonic and sum-frequency generation,2 which require both high power and low (diffraction limited) beam divergence. This can be achieved in an oscillator-amplifier or injection coupled oscillator (ICO) configuration3 where the small (~10 W) master oscillator operates as a low divergence source. For low divergence output, copper vapor lasers are usually fitted with a high-magnification edge-coupled confocal unstable resonator in which a collimated output with diffraction limited divergence builds up within the few round trips (~4) of each laser pulse.
