M. Watanabe et al., SUM-FREQUENCY GENERATION NEAR 194-NM WITH AN EXTERNAL-CAVITY BY SIMULTANEOUS ENHANCEMENT OF FREQUENCY-STABILIZED FUNDAMENTAL LASERS, JPN J A P 1, 33(3B), 1994, pp. 1599-1602
Continuous-wave coherent radiation near 194 nm has been generated by s
um-frequency mixing with simultaneous enhancement of both fundamental
lasers. An output power of 31 muW was obtained at 194 nm. The frequenc
y of a Ti: sapphire laser, which was used as one of the fundamental la
sers, was stabilized with a frequency fluctuation of 80 kHz rms by usi
ng a mode-interference method.
