Phase Locking Quantum Cascade Lasers

Abstract

Talbot external cavity is one of the methods of passive phase-locking linear arrays of laser emitters. Feedback is accomplished in theformer using a flat mirror while a lens is necessary for the latter. Each emitter couples with every other emitter and hence these areknown generically as global coupling methods. Quantum Cascade Lasers (QCLs) are a particularly good system to investigate thesetypes of phase-locking. QCL arrays with their fast time scales, low frequency detunings and small linewidth enhancement factor areposited to lock stably and with good coherency. The long-term vision is to develop a system for mid- and infrared directed energy.
