Generation of tunable single-frequency continuous-wave coherent vacuum-ultraviolet radiation
Abstract
Tunable single-frequency continuous-wave coherent VUV radiation is generated at 143.6 nm by resonant frequency tripling in Mg. The frequency of the output of a frequency-stabilized dye ring laser (spectral width less than 1 MHz) is tuned to the two-photon transition (3s2 1SO - 3s3d 1D2) (430.9 nm) of Mg. A laser power of 0.2 W produces at the third harmonic more than 120,000 photons/sec (1. 8 x 10 to the -13th W). Radiation generated by this method will provide laser VUV spectroscopy of highest spectral resolution.
