InSb/HgCdTe sandwich detector, HgCdTe and GaAs/AlGaAs quantum well infrared photoconductors (QWIPs) present mid-infrared capability in the 3- to 15-m wavelength range. HgCdTe is based on II-VI and µ QWIP is based on the well-developed III-V material systems, which have some advantages WebWe review the history, development, design principles, experimental operating characteristics, and specialized architectures of interband cascade lasers for the mid-wave infrared spectral region. We discuss the present understanding of the mechanisms limiting the ICL performance and provide a perspective on the potential for future improvements. …
Web22 dec. 2024 · High-power and widely tunable continuous-wave optical parametric oscillators (cw OPOs), as mature radiation sources in the mid-infrared range, are limited by their frequency fluctuation. We built a cw OPO working at the near- and mid-infrared ranges and discuss the extent to which its frequency stability is affected by the mechanical … WebCette région spectrale est souvent séparée en deux sous-régions, la région infrarouge à ondes moyennes (MWIR), s’étendant de 3 à 8 µm, et la région infrarouge à ondes longues (LWIR), s’étendant de 8 à 15 µm. Pourquoi des lasers dans l’infrarouge moyen ?
Mid-wave infrared: 3 to 5 μm (defined by the atmospheric window and covered by indium antimonide, InSb and mercury cadmium telluride, HgCdTe, and partially by lead selenide, PbSe). Long-wave infrared: 8 to 12, or 7 to 14 μm (this is the atmospheric window covered by HgCdTe and … Meer weergeven Infrared (sometimes called infrared light and IR) is electromagnetic radiation (EMR) with wavelengths longer than those of visible light and shorter than radio waves. It is therefore invisible to the human eye. IR is generally … Meer weergeven In general, objects emit infrared radiation across a spectrum of wavelengths, but sometimes only a limited region of the spectrum is of interest because sensors usually … Meer weergeven Night vision Infrared is used in night vision equipment when there is insufficient visible light to see. Night vision devices Meer weergeven There is no universally accepted definition of the range of infrared radiation. Typically, it is taken to extend from the nominal red edge of the visible spectrum at 700 nanometers (nm) to 1 millimeter (mm).
