Quantum cascade lasers: ultrahigh-speed operation, optical wireless communication, narrow linewidth, and far-infrared emission (2002, background): “A discussion of proposals related to these efforts is contained in a previous review paper [5].”
Frequency down-conversion of solid-state laser sources to the mid-infrared spectral range using non-oxide nonlinear crystals (2015, background): “On the other hand, strong competition emerged from narrowband and tunable mid-IR QCLs [41] although a single device can tune only over a narrow range.”
THz and sub‐THz quantum cascade lasers (2009, unknown): “The term at the left of the population difference n i − n j is usually called gain cross section and denoted with g c [26].”
Plasmonic Laser Antennas and Related Devices (2008, background): “adjusted continuously from about 3 to 24 μm by tailoring the thickness of the active region quantum well layers, thus covering the entire mid-IR “fingerprint region” [103].”
