Abstract
Quantum cascade lasers with large optical cavities that exhibit low waveguide losses, high saturation intensities, and low beam divergence, emitting between λ ≈ 4.3 and 5.2 μm were studied. Peak-pulsed powers up to 14 W at 15 K and 5 W at 280 K at λ ≈ 5.2 μm are demonstrated. A full-width at half-maximum of only 30° was measured for the transverse far-field pattern of the device operating at λ ≈ 4.3 μm, a significant reduction compared to conventional waveguides. © 2006 IEEE.
