For what is believed to be the first time, a single-longitudinal-mode passively Q-switched Nd:YAG microlaser is used to pump a narrow-bandwidth periodically poled lithium niobate (PPLN) optical parametric generator–optical parametric amplifier (OPG–OPA). Before amplification in the OPA, the output of the OPG stage was spectrally filtered with an air-spaced etalon, resulting in spectroscopically useful radiation (bandwidth, ∼0.05 cm^-1 FWHM) that was tunable in 15-cm^-1 segments anywhere in the signal range 6820–6220 cm^-1 and the idler range 2580–3180 cm^-1. The ability to pump an OPG–OPA with compact, high-repetition-rate, intrinsically narrow-bandwidth microlasers is made possible by the high gain of PPLN. The result is a tunable light source that is well suited for use in portable spectroscopic gas sensors. |
