摘要：

Narrow linewidth terahertz (THz) generation based on difference frequency generation pumped by an all-fiber parametric light source is reported. A pulse source with an ultra-narrow bandwidth is built up as the pump seed source for the succeeding optical parametric amplification (OPA). A pair of phase-conjugated beams is generated as the seed light through all-fiber OPA. The amplified phase-conjugated light beams are injected into 4-N,N-dimethylamino-4'-N'-methyl-stilbazolium 2,4,6-trimethylbenzenesulfonate (DSTMS) to stimulate the emission of terahertz radiation. A THz source with linewidth less than 512 MHz at 1.748 THz pumped by an all-fiber light source is achieved.
