Optical harmonics generation in low-temperature laser-produced plasma

摘要

Harmonics generation of laser radiation ($lambda equals 1.06 $mu@, $tau equals 3 ps) in low-temperature atmospheric plasma and target plasma is investigated. Maximum efficiency was achieved for third harmonics generation ($eta equals 10$+$MIN@3$/). Results of odd harmonics generation (up to eleventh, $lambda equals 96 nm) are reported.
