Near infrared lasers in flow cytometry. [PDF]

open access: yesMethods, 2015
Technology development in flow cytometry has closely tracked laser technology, the light source that flow cytometers almost exclusively use to excite fluorescent probes. The original flow cytometers from the 1970s and 1980s used large water-cooled lasers to produce only one or two laser lines at a time.

Near-infrared laser spectroscopy of NiI [PDF]

open access: yesThe Journal of Chemical Physics, 2004
Laser-induced fluorescence spectrum of NiI in the near infrared region of 714–770 nm has been recorded. Seven bands belonging to three electronic transition systems were observed and analyzed: the (0,0), (1,0), and (2,0) bands of [13.3] 2Σ+-A 2Π3/2 system; the (1,1) and (0,1) bands of [13.9] 2Π3/2-X 2Δ5/2 system; and the (0,0) and (1,0) bands of [13.9]

InAs-Based Quantum Cascade Lasers with Extremely Low Threshold

open access: yesPhotonics, 2022
We report InAs-based quantum cascade lasers (QCLs) operating near 14 µm with a threshold current density Jth as low as 0.6 kA/cm2 at room temperature. The threshold obtained is lower than the Jth of the best reported InP-based QCLs to date without facet ...
