N2 - We report significant improvements in ultraviolet (UV) power generation at elevated pulse-repetition frequencies (10 ≥ kHz) from a frequency-doubled copper-vapor laser (CVL), employing a Ne-H2 buffer gas. In particular, UV powers of 1.3 W and 0.6 W at 255 nm (SHG green) were generated at 10 kHz and 20 kHz, respectively, when using H2 additive in a medium scale (nominally 20 W) CVL oscillator. These results represent improvements of 6.5x and ~100x, respectively, over the UV powers obtained for pure neon-buffer gas. The enhanced UV powers are directly related to the improvement in high-beam quality extraction from the CVL due to the beneficial effects of the H2 add-gas on CVL gain characteristics.
