Abstract :
This paper report on cw UV generation by intracavity frequency doubling of a laser diode pumped Praseodymium (Pr)-doped:YLF laser operating at 523.6 nm. A lens of 50 mm focal length was used to focus the pump beam into the laser crystal. For the generation of UV radiation a beta-barium-borate (BBO)-crystal was placed in the beam waist of the cavity, located between mirrors.
