Quantum Cascade Laser Master-Oscillator Power-Amplifier with 1.5-W Output Power at 300 K

Abstract

We report quantum cascade laser (QCL) master-oscillator power-amplifiers (MOPAs) at 300 K reaching output power of 1.5 W for tapered devices and 0.9 W for untapered devices. The devices display single-longitudinal-mode emission at n=7.26 um and single-transverse-mode emission at TMoo. The maximum amplification factor is 12.2 dB for the tapered devices.
