Abstract
Progress toward the achievement of a compact, sub-kilohertz resolution difference-frequency spectrometer to probe narrow saturated molecular transitions in the 9-11 μm range is reported. The spectrometer, presently generating 40 nW of infrared (IR) power [8], uses a type-I cut AgGaS2 crystal located in a dual-cavity resonator design. A frequency-stabilized alldiode-laser setup was implemented to obtain the required mid-IR spectral purity and frequency tuning range. Further experimental investigations show that a type-II phase-matched AgGaS2 crystal or a walkoff-compensated, two-crystal device would yield at least two times larger conversion efficiency than type-I cut samples. These improvements should help to reach the goal of the microwatt-level output for the IR radiation.
