Journal ArticleDOI
Branching ratios, cross sections, and radiative lifetimes of rare earth ions in solids: Application to Tm3+ and Ho3+ ions in LiYF4
TL;DR: In this paper, branching ratios, cross sections and radiative lifetimes for rare earth ions in solids are considered for Tm and Ho in YLF as a test case.
Journal ArticleDOI
Spectroscopy and modeling of solid state lanthanide lasers: Application to trivalent Tm3+ and Ho3+ in YLiF4 and LuLiF4
TL;DR: In this paper, a theoretical laser model was developed that is easily adapted to any lanthanide ion in a crystal host, and the model was used to predict diode side-pumped laser performance.
Journal ArticleDOI
Comparison of Tm:ZBLAN and Tm:Silica fiber lasers; Spectroscopy and tunable pulsed laser operation around 1.9 μm
Brian M. Walsh,Norman P. Barnes +1 more
TL;DR: In this paper, the authors compared Tm:ZBLAN and Tm-doped silica glass, and showed that the phonon energy in these materials influences both the pump manifold lifetime and the upper laser manifold lifetime.
Journal ArticleDOI
Mid infrared lasers for remote sensing applications
TL;DR: In this article, the capabilities of modeling materials, experimental challenges, material properties, spectroscopy, and prospects for lanthanide-doped mid-infrared solid-state laser devices are presented.
Journal ArticleDOI
Profiling atmospheric water vapor using a fiber laser lidar system
TL;DR: A compact, lightweight, and efficient fiber laser lidar system has been developed to measure water vapor profiles in the lower atmosphere of Earth or Mars and has made preliminary atmospheric measurements.
