| Popis: | An efficient, all-solid-state laser system continuously tunable over the entire 196–204 nm spectral region was demonstrated. This new deep-UV source is based on a novel alexandrite laser/alexandrite-laser-pumped LiF:F 2 +∗∗ color-center laser (CCL) system. Tunable UV generation was realized using type I sum-frequency generation in CLBO of a frequency tripled alexandrite laser and a tunable oscillation of LiF:F 2 +∗∗ CCL. The maximum conversion efficiency obtained at 198 nm wavelength was 23% for input pump power densities of UV ( λ 2 =245 nm ) and IR ( λ 1 =1036 nm ) radiation of 1.5 and 3.3 MW/cm2, respectively, and 25 Hz repetition rate. |
