Abstract
There has been increasing interest in recent years in the development of UV sources based on direct second-harmonic generation from copper-vapor lasers (CVLs). Such sources are attractive for a number of applications, including micromachining, photolithography, and fluorescence diagnostics, in which the high repetition rate (~4 kHz) and the high beam quality of the CVL offer significant ad vantages over other UV-laser sources.
