摘要
利用应变补偿的方法研制出激射波长 λ≈ 3.5— 3.7μm的量子级联激光器 .条宽 2 0 μm,腔长 1 .6mm的 Inx Ga1- x As/Iny Al1- y As量子级联激光器已实现室温准连续激射 .在最大输出功率处的准连续激射可持续 30 min以上 .
Growth of quantum cascade lasers based on strain compensated In x Ga 1 -x As/In y Al 1- y As and operating at a wavelength λ ≈3 5—3 7 micron is reported. Quasi\|continuous wave operation at room\|temperature(RT) has been achieved. For a 1 6mm cavity length and 20 micron ridge waveguide width, quasi continuous wave lasing operation at RT persists more than 30 min.
