    摘要:

    通过研究和优化长波红外量子级联激光器(LWIR QCLs)的光学腔面增透(AR)膜,可提高器件的输出性能。与Al2O3膜系相比,Y2O3 AR膜表现出更高的腔面光学灾变(COMD)水平,两种膜系的光学腔面镀膜均无光束转向效应。对激射波长为8.5 μm的3 mm腔长、9.5 μm脊宽掩埋异质结(BH)LWIR QCL使用Y2O3膜系的金属高反(HR)膜和反射率约0.2%的AR膜,在298 K下获得了2.19 W的最高脉冲峰值功率,较未镀膜器件提高149%。对于连续波(CW)操作,通过优化Y2O3 AR膜的反射率,最高输出功率达到0.73 W,较未镀膜器件提高91%。

    Abstract:

    We report on the performance improvement of long-wave infrared quantum cascade lasers (LWIR QCLs) by studying and optimizing the anti-reflection (AR) optical facet coating. Compared to the Al2O3 AR coating, the Y2O3 AR coating exhibits higher catastrophic optical mirror damage (COMD) level, and the optical facet coatings of both material systems have no beam steering effect. A 3-mm-long, 9.5-μm-wide buried-heterostructure (BH) LWIR QCL of λ ~ 8.5 μm with Y2O3 metallic high-reflection (HR) and AR of ~ 0.2% reflectivity coating demonstrates a maximum pulsed peak power of 2.19 W at 298 K, which is 149% higher than that of the uncoated device. For continuous-wave (CW) operation, by optimizing the reflectivity of the Y2O3 AR coating, the maximum output power reaches 0.73 W, which is 91% higher than that of the uncoated device.
