Abstract

We present new work utilizing frequency modulation stabilization techniques to improve upon our published limits of stabilization. These efforts, based on the Pound-Drever-Hall (PDH) scheme, should permit extension of quantum cascade laser spectroscopy to ultra-high resolution saturation spectroscopy, and cavity-enhanced spectroscopy such as noise-immune cavity-enhanced optical heterodyne molecular spectroscopy
