Abstract: We report on the operation of the Mercury laser with fourteen 4 x 6 cm(2) Yb:S-FAP amplifier slabs pumped by eight 100 kW peak power diode arrays. The system was continuously run at 55 J and 10 Hz for several hours, (2 x 10(5) cumulative shots) with over 80% of the energy in a 6 times diffraction limited spot at 1.047 mu m. Improved optical quality was achieved in Yb:S-FAP amplifiers with magneto-rheological finishing, a deterministic polishing method. In addition, average power frequency conversion employing YCOB was demonstrated at 50% conversion efficiency or 22.6 J at 10 Hz.

Abstract: We present an all solid-state Yb:S-FAP laser system running on the three-level laser transition at 985 run. The pump source was a high fill-factor laser diode bar, with the output reformatted using a two-mirror beamshaping system to produce a rectangular pump beam that focused to a square spot. A nearly on-axis multipassing system was used to obtain four pump passes through a 1.6 mm Yb:S-FAP laser crystal. Gain-switched three-level laser output was achieved with an efficiency of 4.3% with respect to incident pump power. Electro-optic Q-switching produced 0.12 mJ pulses for a pump pulse energy of 11 mJ. Intra-cavity second-harmonic generation yielded a maximum pulse energy at 492.5 nm of 12 mu J. (c) 2006 Elsevier B.V. All rights reserved.

Abstract: We present a diode-pumped, chirped-pulse Yb:S-FAP regenerative amplifier. This regenerative amplifier was developed as a first amplifier in an all-solid-state Yb:S-FAP laser system for laser-Compton X-ray generation. The amplifier delivers pulse energies above 24 mJ at a repetition rate of 50 Hz. Pulse compression reduces pulse widths to approximately 2.0 ps. (C) 2005 Elsevier B.V. All rights reserved.

Abstract: Low-threshold and highly efficient continuous-wave (cw) Yb3+:Y3Al5O12 (Yb:YAG) ceramic laser with near-diffraction-limited beam quality was demonstrated at room temperature. Dual-wavelength operation at 1030 and 1049 nm with 5% transmission of the output coupler was achieved by varying pump power intensity. Slope efficiencies of 79% at 1030 nm and 67% at 1049 nm were achieved for 1-mm-thick Yb:YAG ceramic plate (C-Yb=9.8 at. %) under cw laser-diode pumping. The effect of pump power on the laser emission spectra of both wavelengths is addressed. Excellent laser performance indicates that Yb:YAG ceramic laser materials could be potentially used in high-power solid-state lasers. (c) 2006 American Institute of Physics.

Abstract: A Nd3+:Y3Al5O12 ceramic laser under the hard-UV cutting condition of Xe flashlamp pumping was demonstrated for the first time. By using a 16.4 kW Xe flashlamp and a samarium-doped flow tube, an average laser output power of 386 W was obtained at 1064 nm with a 1.1 at.% Nd3+:Y3Al5O12 ceramic rod of O10 mm x 152 mm. The slope efficiency was measured to be 2.3%, which was the same as for a Nd3+:Y3Al5O12 single crystal rod of similar size. The degradation of output power by the solarization effect was found to be negligible when the UV radiation below 350 nm wavelength was cut by a Sm:glass flow tube. (c) 2005 Elsevier B.V.

Abstract: Diode-pumped solid state lasers have the potential efficiency and repetition rate required for power production. One current candidate for laser materials is an Ytterbium doped ceramic. Yb doped sesquioxides are promising laser materials opening new fields during the research phase to demonstrate ignition and fusion gain (including the fast ignitor concept). We think that cryogenically cooled diode pumped Yb: ceramic laser is the best way to operating at high average power an that all of the operational features of the laser can be demonstrated at an aperture scale of only 10-15 cm.

Abstract: Yttrium aluminum garnet (YAG) (Y3Al5O12) single crystals doped with active species such as Nd and Yb have been used as laser media in solid-state lasers requiring high energy and excellent beam quality. This is because single crystals have extremely high thermal mechanical properties and optical qualities and because they enable high-efficiency laser oscillation. In 1995 the authors, using polycrystalline Nd:YAG, demonstrated a high-efficiency laser that was comparable to a single-crystal laser. Subsequently, single-longitudinal-mode oscillation, green and blue laser oscillation, and ultrashort-pulse laser oscillation were reported. Using the ceramic powder approach, the authors developed a composite laser element with a complicated structure that could not be produced by crystal growth techniques. This review discusses problems of conventional single-crystal growth, the fabrication and characteristics of ceramic lasers, laser oscillation properties (continuous-wave and pulse operation), light-scattering sources in ceramics, and typical applications of ceramic lasers.

Abstract: A new diode-pumped Nd:YAG laser module was designed for use in a high-output-power laser by using a ceramic reflector as an optical pump cavity. In CW operation, a maximum output power of 517 W was obtained with an optical-to-optical conversion efficiency of 38.9 %. In pulse operation, using dual acousto-optic Q-switches whose acousto-optic fields were perpendicular to each other, an average output power of 312 W was obtained with a short pulse width of 55 ns at a 10-kHz repetition rate. This corresponds to a peak output power of 567 kW. The peak-to-peak pulse stability was measured to be less than 2 %, and the average output power stability was measured to be 0.23 %.
