Physics and applications of recent quantum cascade laser active region designs are discussed. Specifically, the use of bound-to-continuum and two-phonon resonance active regions for high temperature, high duty cycle operation is reviewed. Threshold current densities as low as 3kA/cm2 at T=300K, operation with a peak power of 90mW at 425K, and single mode, high power operation up to temperatures above 330K at (lambda) approximately equals 16micrometers are demonstrated. QC lasers able to operate at high duty cycles (50%) on a Peltier cooler were used in a demonstration of a 300MHz free space optical link between two buildings separated by 350m.
