Single-frequency tunable Sb-based VCSELs emitting at 2.3 /spl mu/m
TL;DR: In this article, a comparison between two kinds of single-frequency Sb-based semiconductor VCSELs operating at 2.3 /spl mu/m in continuous-wave regime at room temperature is presented.

TL;DR: The emission from the most active fumarole at the Solfatara volcano near Naples (Italy) was probed for the presence of CO and CH(4), which found the concentrations to be about 3 ppm and 75 ppm, respectively, while actual detection limits for these molecules are around 1 ppb.

High temperature continuous wave operation of Sb-based vertical external cavity surface emitting laser near 2.3 μm
TL;DR: In this paper, the growth conditions and the operation of a diode-pumped AlGaAsSb/GaInSb type-I quantum-well vertical cavity surface emitting laser emitting near 2.3μm in an external cavity configuration are reported.

TL;DR: The direct absorption of CH4 is demonstrated to be possible with high spectral selectivity and the tuning properties made them adaptable to tunable diode laser absorption spectroscopy because they exhibit more than 220 GHz of continuous tuning by temperature or current.

TL;DR: In this paper, a review of the results achieved and a systematic comparison, with such Sb-based lasers emitting near 2.3μm, is presented. And the authors compare the performance of diode-pumped V(E) and electrically-powered DFB-based VCSELs.
