We report on highly efficient third harmonic generation of 1-ps laser pulses in transparent isotropic solid state medium through phase-matched non-collinear four-wave difference-frequency mixing. Third harmonic pulses at 351 nm with 230 μ\muJ energy and 15% energy conversion efficiency were generated in 3-mm-thick UV-grade fused silica sample by use of non-collinear phase matching, cylindrical beam focusing geometry, and pulse-front tilting.

Pademonstruotas efektyvus 1 ps trukmės šviesos impulsų trečiosios harmonikos generavimas, naudojant faziškai sinchronizuotą keturbangį skirtuminio dažnio maišymą skaidrioje izotropinėje kietakūnėje terpėje. Taikant nekolinearų fazinį sinchronizmą, cilindrinį pluoštų fokusavimą bei impulso fronto pokrypį, 3 mm storio lydyto kvarco plokštelėje ties 351 nm bangos ilgiu generuoti trečiosios harmonikos impulsai, kurių energija siekė 230 μ\muJ, o energijos keitimo efektyvumas – 15\%.
