Title: Dual modulation laser line-locking technique for wavelength modulation spectroscopy

Abstract

Disclosed are a method and apparatus for dual modulation of an optical spectroscopy laser. Demodulation is accomplished in a manner resulting in measurement of absorbance of a gas species, as well as stabilization of laser wavelength and baseline noise reduction.
