Some of these instruments have been directed at measurements of atmospher... Quantum cascade laser open-path system for remote sensing of trace gases in Beijing, China [作者：Michel, APM; Liu, PQ; Yeung, JK; Corrigan, P; Baeck, ML; Wang, ZF; Day, T; Moshary, F; Gmachl, CF; Smith, JA,期刊：OPTICAL ENGINEERING, 页码：111125-111125 , 文章类型： Article，,卷期：2010年49-11] Exploiting several key characteristics of quantum cascade (QC) lasers, including wide tunability and room-temperature operation, the Quantum Cascade Laser Open-Path System (QCLOPS) was designed for the detection of a ... Use of quantum cascade lasers for detection of explosives: progress and challenges [作者：Bauer, C; Willer, U; Schade, W,期刊：OPTICAL ENGINEERING, 页码：111126-111126 , 文章类型： Article，,卷期：2010年49-11] Detection of explosives is an emerging task for maintaining civil security. Optical methods and especially tunable diode laser spectroscopy are discussed as means for providing fast and reliable data. Selective and sensi... Progress in high-performance quantum cascade lasers [作者：Lyakh, A; Maulini, R; Tsekoun, AG; Patel, CKN,期刊：OPTICAL ENGINEERING, 页码：111105-111105 , 文章类型： Article，,卷期：2010年49-11] Because of their compact size, reliability, tunability, and convenience of direct electrical pumping, quantum cascade lasers have found a number of important civilian and defense applications in the midwave infrared and ... Quantum cascade lasers: high-power emission and single-mode operation in the long-wave infrared (lambda > 6 mu m) [作者：Troccoli, M; Wang, XJ; Fan, JY,期刊：OPTICAL ENGINEERING, 页码：111106-111106 , 文章类型： Article，,卷期：2010年49-11] We present an overview of our recent results on the growth, fabrication, and characterization of high-power long-wave infrared quantum cascade lasers with multimode and single-mode waveguides. Powers of up to 1.2 W at wa... Nonlinear gain behavior in injectorless quantum cascade lasers [作者：Katz, S; Vizbaras, A; Boehm, G; Amann, MC,期刊：OPTICAL ENGINEERING, 页码：111107-111107 , 文章类型： Article，,卷期：2010年49-11] The gain spectra of a continuous wave operating injectorless quantum cascade lasers are presented. These are extracted by the Hakki-Paoli method from electroluminescence measurements. The device operates around 7.4 mu m ... Electron leakage and its suppression via deep-well structures in 4.5-to 5.0-mu m-emitting quantum cascade lasers [作者：Botez, D; Shin, JC; Kumar, S; Mawst, LJ; Vurgaftman, I; Meyer, JR,期刊：OPTICAL ENGINEERING, 页码：111108-111108 , 文章类型： Article，,卷期：2010年49-11] The equations for threshold-current density J(th) and external differential quantum efficiency eta(d) of quantum cascade lasers (QCLs) are modified to include electron leakage and the electron-backfilling term corrected ...
