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 λ = 7.26 µm and single-transverse-mode emission at TM(00). The maximum amplification factor is 12 dB for the tapered devices.
我们报道了在300 K温度下的量子级联激光器（QCL）主振荡功率放大器（MOPA），对于锥形器件，其输出功率达到1.5 W，对于非锥形器件，输出功率达到0.9 W。这些器件在λ = 7.26 µm处呈现单纵模发射，在TM(00)处呈现单横模发射。对于锥形器件，最大放大倍数为12 dB。
