Development and study of high-power quantum-cascade lasers emitting at 4.5 – 4.6 μm

Quantum-cascade room-temperature 4.5 – 4.6 μm lasers with different numbers of quantum cascades are developed and studied. It is shown that losses at the metallised sidewalls of the ridge waveguide considerably increase the threshold current density. It is demonstrated that the current density needed to overcome the internal and outcoupling losses in lasers with 30 quantum cascades is an order of magnitude lower than in lasers with 15 quantum cascades.

10-W 4.6-μm quantum cascade lasers

Ridge quantum-cascade lasers emitting near 4.6 μm are fabricated and their power and spectral characteristics are studied. Stable pulsed lasing with an output optical power exceeding 10 W (more than 5 W from one facet) at room temperature is demonstrated. (paper)

High-power (>1 W) room-temperature quantum-cascade lasers for the long-wavelength IR region

Ridge quantum-cascade lasers emitting at a wavelength near 8 μm are fabricated and studied. Lasing at room temperature with a maximum output peak power exceeding 1 W from one facet is demonstrated. (paper)
