Abstract : An instrumentation grant for the purchase of an tunable diode laser-amplifier, a rf synthesizer, and a rf spectrum analyzer is used to significantly enhance current research and support new investigations in optical parametric oscillators and wide-span optical frequency comb generation. Areas of research that benefit from the new capabilities include precision frequency metrology, optical communications, and multi-wavelength information processing. The fabricated diode laser at 790 nm has been utilized to generate tunable 1.6 um light using difference-frequency mixing in a quasi-phase matched periodically-poled lithium niobate substrate. It will also be used to pump an optical parametric oscillator for the generation of tunable 1.5-1.6 um radiation in the mW power range. The spectrum analyzer and synthesizer are to be used for evaluating the beat-note and phase noise characteristics of optical parametric oscillators and optical frequency comb generators.
