Ra. Ganeev et T. Usmanov, CONTINUOUS FREQUENCY TUNING OF A PICOSECOND NEODYMIUM-GLASS LASER IN THE UV AND VUV, Technical physics, 43(5), 1998, pp. 555-561
The results of an investigation of continuous frequency tuning of a ne
odymium laser in the UV and VUV ranges are reported. Generation of the
sum frequency of second harmonic radiation and the radiation from a p
arametric light generator in the UV region (338-366 nm) is achieved. T
he optimal conditions for tuning UV radiation in the range 113.5-117.0
nm in third-harmonic generation processes in xenon and its mixtures w
ith other gases are investigated. A third-harmonic generation efficien
cy of similar to 5 x 10(-4) and a tuning range > 2600 cm(-1) are obtai
ned in the VUV range investigated. (C) 1998 American Institute of Phys
