Optical harmonics generation in low-temperature laser-produced plasma

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<SUP>-3</SUP>). Results of odd harmonics generation (up to eleventh, (lambda) equals 96 nm) are reported.
