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
1 J/pulse Q-switched 2 µm solid-state laser
Jirong Yu,Bo C. Trieu,Ed A. Modlin,Upendra N. Singh,Michael J. Kavaya,Songsheng Chen,Yingxin Bai,Paul Petzar,Mulugeta Petros +8 more
TL;DR: This is the first time to the authors' knowledge that a 2 microm laser has broken the joule per pulse barrier for Q-switched operation, and the total system efficiency reaches 5% and 6.2% for single- and double-pulse operation, respectively.
Journal ArticleDOI
High-energy 2μm Doppler lidar for wind measurements
Grady J. Koch,Jeffrey Y. Beyon,Bruce W. Barnes,Mulugeta Petros,Jirong Yu,Farzin Amzajerdian,Michael J. Kavaya,Upendra N. Singh +7 more
TL;DR: In this article, a coherent Doppler lidar at 2 m wavelength has been built with higher output energy 100 mJ than previously available, based on diode-pumped Ho:Tm:LuLiF, a recently developed laser material that allows more efficient energy extraction.
Journal ArticleDOI
Side-line tunable laser transmitter for differential absorption lidar measurements of CO2: design and application to atmospheric measurements.
Grady J. Koch,Jeffrey Y. Beyon,Fabien Gibert,Bruce W. Barnes,Syed Ismail,Mulugeta Petros,Paul Petzar,Jirong Yu,Edward A. Modlin,Kenneth J. Davis,Upendra N. Singh +10 more
TL;DR: A 2 microm wavelength, 90 mJ, 5 Hz pulsed Ho laser is described with wavelength control to precisely tune and lock the wavelength at a desired offset up to 2.9 GHz from the center of a CO(2) absorption line.
Journal ArticleDOI
125-mJ diode-pumped injection-seeded Ho:Tm:YLF laser.
TL;DR: The high power and high beam quality of this diode-pumped, room-temperature Ho:Tm:YLF power oscillator make it well suited for use as a coherent wind lidar transmitter on a space platform.
