Yb-Sensitized Rare-Earth Doped Optical Glasses
The temperature e ect upon infrared-to-visible frequency upconversion uorescence emission in o -resonance infrared excited Yb-sensitized rare-earth doped optical glasses is theoretically and experimentally investigated. We have examined samples of Er3+/Yb-codoped Ga2S3:La2O3 chalcogenide glasses and germanosilicate optical bers, and Ga2O3:La2O3 chalcogenide and uoroindate glasses codoped with P...
متن کاملOptical and EPR properties of BaY2F8 single crystals doped with Yb
Yb doped materials have turned out to be relevant for efficient high-power continuous-wave lasers, up to the kilowatt class. In the present paper we analyze optical and EPR properties of BaY2F8:Yb (5wt.%) single crystals obtained using Czochralski method. The Yb energy levels for the crystal are as follows: F7/2 (0, 216, 430, 530 cm), F5/2 (10277, 10395, 10735 cm ). BaY2F8 highly doped with Yb ...
متن کاملSolid-state Laser Cooling of Ytterbium-doped Tungstate Crystals
Anti-Stokes fluorescence can be used to cool a material if its radiative quantum efficiency is nearly unity. Until recently, the only solid which had shown net cooling was an ytterbium-doped heavy metal fluoride glass. Reasons for the lack of success with other materials include energy transfer to unwanted impurities, trapping of the fluorescence by internal reflection and reabsorption, and non...
متن کاملGamma Radiation Effects in Yb-Doped Optical Fiber
Determination of the radiation response of doped-fiber laser materials, systems and components to relevant ionizing radiation fluxes is central to the prediction of long-term fiber-based laser performance/survivability in adverse and/or space-based environments. It is well known that optical elements that are placed into orbit around the Earth experience harsh radiation environments that origin...
متن کاملOptical Reorientation in Dye-doped Liquid Crystals
The nonlinear optical properties of liquid crystals received considerable attention in the past decades and were reviewed by various authors. Harmonic generation in liquid crystalline phases and optical reorientation of nematics are examples of nonlinearities studied in detail. The present paper deals with the latter effect, paying special attention to the influence of absorption on the process...
