Journal ArticleDOI
Upconversion-pumped luminescence efficiency of rare-earth-doped hosts sensitized with trivalent ytterbium
Ralph H. Page,Kathleen I. Schaffers,P. A. Waide,J.B. Tassano,Stephen A. Payne,William F. Krupke,William K. Bischel +6 more
TL;DR: In this article, the upconversion luminescence efficiencies of phosphors that generate red, green, and blue light were discussed. But the main contribution is the quantitative measurement of this upcon conversion efficiency, based on the use of a calibrated integrating sphere, determination of the fraction of pump light absorbed, and careful control of the pump-laser-beam profile.
Journal ArticleDOI
Cr/sup 2+/-doped zinc chalcogenides as efficient, widely tunable mid-infrared lasers
Ralph H. Page,Kathleen I. Schaffers,Laura D. DeLoach,G.D. Wilke,F.D. Patel,J.B. Tassano,Stephen A. Payne,William F. Krupke,K.-T. Chen,Arnold Burger +9 more
TL;DR: In this paper, transition-metal-doped zinc chalcogenide (ZnS:Cr) and ZnSe:Cr (using a MgF/sub 2/:Co/sup 2+/ laser pump source) were used for mid-infrared laser applications.
Journal ArticleDOI
Continuous-wave broadly tunable Cr2+:ZnSe laser.
Gregory J. Wagner,Timothy J. Carrig,Ralph H. Page,Kathleen I. Schaffers,Jean-Oliver Ndap,X. Ma,Arnold Burger +6 more
TL;DR: Room-temperature operation of an all-solid-state broadly tunable continuous-wave Cr(2+):ZnSe laser is reported, and continuous tunability from 2138 to 2760 nm is demonstrated.
Journal ArticleDOI
The mercury project: a high average power, gas-cooled laser for inertial fusion energy development
Andy J. Bayramian,P. Armstrong,E. Ault,Raymond J. Beach,Camille Bibeau,John A. Caird,R. Campbell,B. Chai,Jay W. Dawson,Christopher A. Ebbers,Alvin C. Erlandson,Y. Fei,Barry L. Freitas,R. Kent,Z. Liao,T. Ladran,Joseph A. Menapace,B. Molander,S.A. Payne,N. Peterson,M. Randles,Kathleen I. Schaffers,S.B. Sutton,J. Tassano,S. Telford,E. Utterback +25 more
TL;DR: The Mercury laser project as discussed by the authors developed key technologies within an architectural framework that demonstrates basic building blocks for scaling to larger multi-kilojoule systems for inertial fusion energy (IFE) applications.
Journal ArticleDOI
Broadly tunable compact continuous-wave Cr 2+ :ZnS laser
Irina T. Sorokina,Evgeni Sorokin,Sergey B. Mirov,Vladimir V. Fedorov,Valery V. Badikov,Vladimir Panyutin,Kathleen I. Schaffers +6 more
TL;DR: A continuous-wave, room-temperature Cr(2+) ZnS laser that is compact and tunable over 700 nm that is intrinsically polarized and sensitization of the output radiation by a few milliwatts of the visible and near-infrared radiation.
