| Research Abstract |
In this project, we developed novel light sources having a multifrequemcy/broadband spectrum based on a stimulated Raman effect pumped by continuous-wave (cw) and ultrashort pulse lasers. A three-primary-color emission that could be used for the generation of an extremely highly repetitive cw optical pulse train was generated through phase-matched four-wave mixing process in the dispersion-compensated high-finesse optical cavity. In addition, our newly developed molecular modulation scheme allowed for the generation of broadband deep-ultraviolet radiation that corresponded to a duration of 10 femtosecond and the demonstration of dramatic enhancement of the detection limit of explosive chemical compounds.
