Abstract :
Summary form only given. The quantum-cascade (QC) distributed feedback laser operating in the mid-infrared promises to be an excellent tool for remote sensing applications as well as in situ monitoring of trace gases. In addition to the high cw power, the QC laser exhibits excellent intrinsic frequency stability. We report here on the characterization of the spectral noise density of a 8.5 /spl mu/m QC laser operating cw at liquid nitrogen temperatures.
