介绍了在400K以上连续波下工作的高功率量子级联激光器。该材料采用低压金属有机气相外延生长，加工成窄埋异质结构激光器。波长8.38μm、长3mm、宽7.5μm的涂层激光器在300K下获得了204mW的连续波输出功率。该器件在400K以上的连续波模式下工作，比以前的qcl最大连续波温度工作高约60K。通过加速老化试验获得的初步可靠性数据表明，激光器具有显著的鲁棒性。
High-power quantum cascade lasers (QCLs) working in continuous wave (cw) above 400K are presented. The material was grown by low-pressure metal organic vapor-phase epitaxy and processed into narrow buried heterostructure lasers. A cw output power of 204mW was obtained at 300K with an 8.38μm wavelength, 3mm long and 7.5μm wide coated laser. The device operates in cw mode above 400K, which exceeds the previous maximum cw temperature operation of QCLs by approximately 60K. Preliminary reliability data obtained by accelerated aging tests indicate a remarkable robustness of the lasers.
