Excited-State Absorption in High-Power Mid-Infrared Quantum Cascade Lasers

Not Accessible

Your library or personal account may give you access

Abstract

The loss due to excited-state absorption into the continuum was calculated for high-power mid-infrared quantum cascade lasers. We find this loss to be a significant fraction of the gain at the laser wavelength.
