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 lambda = 7.26 mu m and single-transverse-mode emission at TM00. The maximum amplification factor is 12 dB for the tapered devices.
