3 W near-diffraction-limited power from high-index-contrast photonic-crystal quantum cascade lasers

Phase locking, via resonant leaky-wave coupling, of five 8.36 μm-emitting quantum cascade lasers has provided in-phase-mode operation to 3 W with 1.5 × diffraction limit lobe-width and 2.45 W emitted in the main far-field lobe.
