Abstract
The linewidth enhancement factor (alpha-factor) of a commercially available 6.1 mum InGaAs/InAlAs distributed-feedback quantum cascade laser capable of continuous-wave operation with a Peltier cooler and its current dependence were investigated. alpha tended to increase slowly with an increase in current. alpha, probably affected by detuning, was still smaller than that of conventional 1.55 mum semiconductor laser diodes.
