Abstract

Relative frequency stabilization of two 8.5-micron quantum cascade lasers to 5.6 Hz was demonstrated. Stabilization was performed, to separate optical cavities, using highly optimized servo loops. A 5.6 Hz FWHM beat notes that were stable for periods up to a second, were presented between these two cavities. This represented an effective reduction from free-running linewidth of these lasers of 150 kHz of over 25,000.
