ABSTRACT We present a high-power, high-efficiency and low threshold laser prototype based on doped ceramic Yb3+:YAG. We achieved an output power of 9 W with a slope efficiency of 73% and a threshold of 1 W at 1030 nm in quasi-Continuous Wave (QCW). Moreover, we obtained an output power 7.7 W with a slope efficiency of 60% in Continuous Wave (CW). Finally, a characterization of a low losses tunable cavity for several laser wavelengths with an output power exceeding 5 W is reported. (C) 2009 Optical Society of America

    • "The situation remained unchanged until 1995, when Ikesue et al. [1] [7] first demonstrated the possibility of fabricating transparent Nd:YAG ceramics of sufficient quality for solid-state lasers with reasonable efficiency. Since then, quite a few studies on YAG laser ceramics have been reported, concerning on Nd:YAG [2] [8] [9], Yb:YAG [10] [11] [12], Tm:YAG [13] [14], Ho:YAG [15] [16] and Er:YAG [17] [18] [19] and other materials. There are two basic methods to fabricate YAG transparent ceramics. "

    ABSTRACT: Influence of Y2O3 commercial powders preheat-treating in oxygen atmosphere on solid-state reactive sintering of Nd doped yttrium aluminum garnet (Nd:YAG) transparent ceramics was investigated. The ceramics were fabricated by solid-state reactive sintering of commercial α-Al2O3, Nd2O3 and either untreated or heat-treated Y2O3 powders. It was found that the preliminary heat-treatment of the Y2O3 powders in oxygen atmosphere may reduce the internal porosities of the Y2O3 powder and optimize the matching with α-Al2O3 powder, increases relative density of the green body and transparency of ceramics. The highest transparency was achieved when the Y2O3 powder was pretreated at 1000 °C. The in-line transmittances are 83.7% and 82.1% at the wavelength of 1064 nm and 400 nm, respectively. Basic reasons of the Y2O3 powders preheat-treatment influence on the microstructure and optical transmission of Nd:YAG transparent ceramics were established.

    ABSTRACT: In this work we expose a recently developed theoretical model for the analysis of the measurements obtained with the so-called pinhole method, for the determination of the upper level lifetime in materials where the superimposition between fluorescence and absorption spectra determines significant radiation trapping effect. Under fairly general conditions the fluorescence decay curve after a pulsed excitation of the sample obtained with this experimental set-up can be conveniently described by a double exponential functional form. The faster of the two decay times is close to the intrinsic fluorescence lifetime, with a difference that can be calculated with geometrical considerations. The theoretical results were tested with a suitably designed experiment, where the upper level lifetime of the laser transition of some Yb doped samples were investigated, obtaining results that are consistent with literature data and in good agreement with the theoretical results as for the temporal dependence of the fluorescence decay.

    ABSTRACT: We present the first laser oscillation achieved on Yb-doped Sc2O3 and Lu2O3 ceramics with a level of doping as low as 1 at %, under quasi-continuous wave pumping at 968 nm. Ceramic samples reached comparable performances in terms of tunability ranges, which exceeds 41 nm, and laser output powers. In particular, with the former sample emitting at 1040.5 nm we measured a maximum output power of 2.2 W with a corresponding slope efficiency of η = 59%. The latter medium delivered 1.8 W with a slope of η = 45% at 1032.5 nm while at 1078 nm we measured 1.5 W with η = 34%. Finally, we report the measured level of the Amplified Spontaneous Emission (ASE) for both samples, which was found to be less than 0.1 mW at the maximum pump power.
