Narrowband tunable VUV radiation generated by nonresonant sum- and difference-frequency mixing in xenon and krypton
Nonresonant sum- and difference-frequency mixing of the fundamental ..omega../sub L/ and the second harmonic ..omega../sub UV/ radiation of a powerful narrowband pulsed dye laser system excited by an Nd:YAG laser (lambda/sub L/ = 5500--6500 A) generates intense VUV radiation in krypton and xenon with the frequency ..omega..VUV = 2..omega..UV +- ..omega../sub L/. The sum-frequency is tunable in spectral regions of negative dispersion between 1100 and 1300 A. The maximum VUV pulse power exceeds 20 W (5 x 10/sup 10/ photons/pulse). VUV light pulses with up to 60 W (2.3 x 10/sup 11/ photons/pulses) are provided by the difference-frequency at wavelengths between 1850 and 2070 A. In addition the conversion process ..omega..VUV = 2..omega..IR (..omega../sub IR/ is the frequency of the Nd:YAG laser) generates radiation in the wavelength range of 1595--1866 A. With present laser systems the tuning range of the difference-frequency could be extended to wavelengths as short as 1226 A. The sum- and difference-frequency conversion will thus provide intense coherent VUV light continuously tunable between 1100 and 2100 A.
