据报道，量子级联激光器的连续波操作温度高达 312 开尔文。该器件被制造为埋入式异质结构激光器，在两个激光面上都具有高反射涂层，从而实现连续波操作，光输出功率范围从 292 开尔文的 17 毫瓦到 312 开尔文的 3 毫瓦，发射波长为 9.1 微米。结果证明了量子级联激光器作为连续波中红外光源用于高分辨率光谱、化学传感应用和自由空间光通信系统的潜力。
Continuous wave operation of quantum cascade lasers is reported up to a temperature of 312 kelvin. The devices were fabricated as buried heterostructure lasers with high-reflection coatings on both laser facets, resulting in continuous wave operation with optical output power ranging from 17 milliwatts at 292 kelvin to 3 milliwatts at 312 kelvin, at an emission wavelength of 9.1 micrometers. The results demonstrate the potential of quantum cascade lasers as continuous wave mid-infrared light sources for high-resolution spectroscopy, chemical sensing applications, and free-space optical communication systems.
