摘要：

Recent progresses about optical pumped tunable terahertz(THz) sources are interviewed,including THz parametric oscillation(TPO) and difference frequency generation(DFG). We develop high efficiency and high power surface-emitted TPO, as well as DFG with nonlinear crystals. A novel scheme for the high efficiency DFG source based on the Cherenkov phase-matching technology is comprehensively investigated in both bulk crystals. The widely tunable optical THz radiation is also researched based on the organic nonlinear 4-N,N-dimethylamino-4′-N′-methylstilbazolium 2,4,6-trimethylbenzenesulfonate(DSTMS) crystal.
