Linewidth Enhancement Factor of 6.1-μm Quantum Cascade Laser at Near Room-Temperature

Not Accessible

Your library or personal account may give you access

Abstract

The linewidth enhancement factor (α) of a quantum cascade laser near room-temperature and its current dependence were investigated. The a, probably affected by the detuning, was still smaller than that of conventional semiconductor laser diodes.
