Abstract
Generation of wide tunable laser radiation from 188 nm in UV til 7.7 micrometers in IR is reported in our laboratory using a single commercially available Nd:YAG laser as basic pump. Techniques employed are sum-frequency mixing and harmonic generation for the UV while for the IR we employ difference- frequency mixing. The nonlinear crystal used include BBO, LBO, CLBO, LB4, KTP, RTP, KTA and LiIO3. A maximum conversion efficiency over 2-0 percent is realized for both in UV and IR generation. We have obtained some spectra of DNA, RDX in the UV while those of polystrene film and Methane gas in the IR with the generated radiation.
