Growth and Characterization of Ytterbium Doped Silicate Crystals for Ultra-Fast Laser Applications
Diode-pumped solid-state lasers (DPSSL) have predominated over waveguide lasers and fiber lasers when considering the efficiency and operability since the first realization of laser-diode pumped Yb-doped laser at room temperature (Lacovara et al., 1991). As a rule of thumb, DPSSL are preferable for devices operating with high peak power, whereas low-threshold and high-gain operation is much eas...
متن کاملTunable laser operation of ytterbium in disordered single crystals of Yb:NaGd(WO4)2.
Lasing of Yb3+ in a disordered single crystal host, NaGd(WO4)2, is reported. Pump efficiencies as high as 20% and slope efficiencies as high as 30% are achieved for both sigma- and pi-polarizations with Ti:sapphire laser pumping. The emission of Yb:NaGd(WO4)2 is centered near 1030 nm. Tunability between 1016 and 1049 nm is obtained with a Lyot filter.
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 کاملSingle-frequency 1 W hybrid Brillouin/ytterbium fiber laser.
A high-power hybrid Brillouin/ytterbium fiber laser has been demonstrated with an output power of 1 W. The laser operates in the single-frequency regime with an optical signal-to-noise ratio greater than 55 dB in a 0.1 nm bandwidth.
متن کاملImplant Bed Preparation with an Erbium, Chromium Doped Yttrium Scandium Gallium Garnet (Er,Cr: YSGG) Laser Using Stereolithographic Surgical Guide.
BACKGROUND Implant bed preparation with laser is taken into consideration owing to the increased interest in use of lasers in hard tissue surgery. The purpose of this study is to determine the deviations in the position and inclination between the planned and prepared implant beds with Erbium, Chromium doped Yttrium Scandium Gallium Garnet (Er,Cr:YSGG) laser using stereolithographic (SLA) surgi...
