High dynamic range laser dispersion spectroscopy of saturated absorption lines

High dynamic range laser dispersion spectroscopy of saturated absorption lines

A spectroscopic detection of molecular dispersion based on frequency-chirped laser is presented. Unlike non-linear direct absorption methods yielding line saturation, this method provides linear signal response and accuracy over a wide range of sample concentrations.
