Abstract :
The pulsed output of a Yb-doped fiber amplifier was frequency doubled and quadrupled to generate visible and UV radiation. When pumped with 150-200 mW at 980 nm and seeded at 1064 nm, the amplifier produced an average power of 90 mW at 1064 nm, 45 mW at 532 nm, and 1.4 mW at 266 nm. These results indicate that frequency-converted fiber lasers and amplifiers will be able to replace conventional tunable UV sources (e,g,, frequency-converted dye lasers) in a number of applications.
