Paper Abstract

Compact DPSS UV sources are of interest for replacing Ar-Ion lasers in applications that require cw or quasi-cw laser radiation. One way to generate UV light at 355nm and 266nm is by modelocking an IR Nd:YVO4 laser and converting the ps pulses into the second, third, and fourth harmonic. The mechanism of choice is passive modelocking using a Saturable Bragg Reflector (SBR). We have developed an air-cooled system capable of UV output powers in excess of 6W. Laser performance as well as lifetime data will be presented for wavelengths at 355nm and 266nm.
