Abstract

We report on the improvement of a tunable diode-laser-based difference-frequency spectrometer using AgGaS2 nonlinear crystal. This spectrometer is being developed as an alternative to CO2 laser spectrometers in the 9 μm to 11 μm range. We use a type-II cut crystal as a part of the improvement compared to a type-I cut, which was used in our preliminary set-up. Using a Fabry-Perot cavity to enhance the 780-nm power (35 mW in front of the cavity) and 120 mW of the 843-nm radiation, 30-nW power of the tunable 10-μm radiation is detected. This power level is enough to investigate the linear absorption spectroscopy of SF6. Doppler limited spectra over 2 GHz are recorded, showing the wide tunability of the spectrometer.
