英国的研究人员研制出了目前波长最短的室温量子级联激光器(QCL)。该仪器基于应力补偿InGaAs/AlAsSb系统,波长仅为3.1μm,输出功率为8mW。近来,波长在3～4μm的高性能QCL可直接利用磷化铟基底InGaAs/AllnAs传统材料直接制造。然而,现在的研究热点却转向了包括-锑化物在内的异质 British researchers have developed the shortest wavelength at room temperature quantum cascade laser (QCL). The instrument is based on a stress-compensated InGaAs / AlAsSb system with a wavelength of only 3.1 μm and an output power of 8 mW. Recently, the high-performance QCL with a wavelength of 3 to 4 μm can be fabricated directly from the InGaAs / AllnAs conventional materials based on indium phosphide substrates. However, the current research focuses on the heterogeneity including antimonide
