Abstract
There is continued interest in using copper vapor lasers (CVL) in applications requiring high beam quality, such as pumping of solid-state laser materials (e.g., Ti:sapphire) and nonlinear frequency conversion. To obtain high-beam quality (i.e., low divergence), copper vapor lasers usually employ high-magnification edge-coupled confocal unstable resonators, which are capable of generating diffraction-limited output within the gain duration of the CVL.
