Abstract

Second harmonic generation of a copper HyBrID laser oscillator was performed at 15 kHz. 5.1WUV (255 nm) total average power at 15 kHz were generated in two b-barium borate (BBO) crystals by frequency doubling of two 511 nm beams from a single unpolarized HyBrID copper vapor laser. The beam quality factors of the UV emission are found to be M2 X ¼ 30 2 and M2 Y ¼ 24 2. These two UV beams, combined at the focal point of a focusing objective, may enable high repetition rate UV laser processing.
