K. Matsubara et al., SUBMILLIWATT CONTINUOUS-WAVE COHERENT-LIGHT GENERATION NEAR 214.5 NM BY 2-STAGE FREQUENCY-DOUBLING OF A DIODE-LASER, JPN J A P 1, 37(9A), 1998, pp. 4838-4839
We generated 0.64 mW of continuous-wave coherent light near 214.5 nm b
y using an all-solid-state light source. In this source, IR light from
a master-laser and power-amplifier system based on diode lasers was f
requency-quadrupled in two successive frequently-doubling stages. A co
ntinuous frequency-scanning range of more than 7 GHz was observed in t
he 214-215 nm wavelength region.
