Abstract

Summary from only given. We demonstrate the successful frequency stabilization of two QCLs to separate optical cavities using highly optimized servo loops based on the Pound-Drever-Hall technique. We present 5.6 Hz FWHM beat notes between these two systems that are stable for periods up to a second. This represents an effective reduction from the recently recorded free-running linewidth of these same lasers of 150 kHz of over 25,000.
