中红外（IR）量子级联激光器（QCL）的性能现在达到成熟水平，其能够实现各种应用，这些应用需要能够具有高光束质量的瓦特范围输出功率的紧凑型激光源。我们审查的基本设计问题和当前的性能限制，专注于InGaAs/AlInAs/InP QCL的发射在3-6 μ m的波长范围。变质材料拓宽了用于访问短发射波长（λ 5 W）的可用成分，在短脉冲操作中具有衍射限制光束的前端面输出功率。
The performances of mid-infrared (IR) quantum cascade lasers (QCLs) are now reaching a maturity level that enables a variety of applications which require compact laser sources capable of watt-range output powers with high beam quality. We review the fundamental design issues and current performance limitations, focusing on InGaAs/AllnAs/InP QCLs with emission in the 3-6 mu m wavelength range. Metamorphic materials broaden the available compositions for accessing short emission wavelengths (lambda 5W front-facet output powers with diffraction-limited beams in short-pulse operation.
