摘要：

A long-wavelength cw difference-frequency source based on the use of low-power AlGaAs diode lasers and a critically phase-matched (CPM) silver thiogallate (AgGaS2) nonlinear crystal is reported. The device uses a standing-wave dual-resonator scheme to enhance both near-infrared lasers. For 7 mW of 778.2-nm and 275 mW of 842.5-nm input powers, 40 nW of 10.2-mu m radiation is generated by a preliminary setup. A mu W-level range output power is expected after optimization of the device optical components. This compact tunable source will allow Fabry-Perot high-resolution Doppler-free spectroscopy of spherical molecules, such as OsO4 or SF6, in the 9-11 mu m range as an alternative source to frequency-stabilized CO2 lasers.
