Superbroadband laser for visible and UV spectral regions

摘要

The analysis of simultaneous second and fourth harmonic generation of superbroadband LiF:F$-2$/$+$MIN$/ color center laser radiation in different nonlinear crystals is presented. The experiments have shown high laser and harmonic conversion efficiencies. Simultaneous generation of continuous spectra in near IR, visible and Uv spectral regions, and multiline oscillation with high spectral resolution $Delta@v $LS 5 cm$+$MIN@1$/ have been obtained.
