Abstract

A cw tunable spectrometer based on the difference frequency generation (DFG) using the nonlinear crystal AgGaS₂ (1 = 40 mm, non-critical type I phase matching) and two diode lasers was constructed. With this system the authors are able to cover the wavenumber region around 2050 - 2150 cm^-1. In this region molecular gases like CO, N₂O and NO have pronounced absorption lines excluding interferences from other atmospheric gases. With diode lasers as pump source (690) and 810 nm) the authors are able to detect this trace gases as well as to measure line broadening coefficients and spacing of several NO-doublets.
