We fabricated waveguides in Pr:SrAl(12)O(19) crystals by direct femtosecond laser writing. The propagation losses were calculated to be as low as 0.16 dB/cm at a wavelength of 633 nm. Laser oscillation in a diode-pumped waveguide at a wavelength of 643.5 nm was realized. The output power of the waveguide laser was 28.1 mW at a slope efficiency of 8%. 相似文献

The spin magnetic moment $\mu^{\overline{p}}_{s}$ of the antiproton can be determined by comparing the measured transition frequencies in $\overline{p}^4$ He?+? with three-body QED calculations. A comparison between the proton and antiproton can then be used as a test of CPT invariance. The highest measurement precision of the difference between the proton and the antiproton spin magnetic moments to date is 0.3%. A new experimental value of the spin magnetic moment of the antiproton was obtained as $\mu^{\overline{p}}_{s} = -2.7862(83)\mu_{N}$ , slightly better than the previously best measurement. This agrees with $\mu^{p}_{s}$ within 0.24%. In 2009, a new measurement with antiprotonic 3He has been started. A comparison between the theoretical calculations and experimental results would lead to a stronger test of the theory and address systematic errors therein. A measurement of this state will be the first HF measurement on $\overline{p}^3$ He?+?. We report here on the new experimental setup and the first tests. 相似文献

The paper is devoted to the functional inequality (called by us Hlawka’s functional inequality) $$f(x+y)+f(y+z)+f(x+z)\leq f(x+y+z)+f(x)+f(y)+f(z)$$ for the unknown mapping f defined on an Abelian group, on a linear space or on the real line. The study of the foregoing inequality is motivated by Hlawka’s inequality: $$\|x+y\|+\|y+z\|+\|x+z\|\leq\|x+y+z\|+\|x\|+\|y\|+\|z\|,$$ which in particular holds true for all x, y, z from a real or complex inner product space. 相似文献

Summary. Thin-film electrodes allow the manufacturing of flat batteries of variable design. Their electric performance is better than
that of customary cells because of a larger contact area between anode and cathode and better utilization of the electrochemically
active materials. Bipolar thin-film electrodes for the rechargeable alkaline zinc/manganese dioxide system were assembled
using graphite-filled plastics (high-density polyethylene and polyisobutylene). In a different approach, extremely thin electrodes
were obtained using 25 μm thick foils made of non-conductive micro-porous polypropylene. The electroactive materials were
electrolytically deposited into the pores of the previously metallized foil, providing the required conductive connection
through the plastic matrix by themselves. Cycle behavior, cumulated capacities, and energies of batteries with up to two bipolar
units were measured. At this early stage of development, batteries based on graphite-filled polymer foils showed better results
with regard to storage capacity per unit area and to cycle life. Prototypes based on micro-porous polypropylene suffered from
the relatively small fraction of pore volume available for the deposition of active material (about 38%) and from current
collector corrosion.

Income compensation functions based on preference relations that are not required to be transitive or complete are studied, and a nearly complete theory of compensated consumer behaviour is developed, using a weaker version of representability. 相似文献

This paper reports on the use of Auger electron spectroscopy (AES)/ depth profile analysis for the investigation of plasma-sprayed coatings. Prior to spraying the St 37 substrates are heated to 300 °C or 500 °C for ceramic or metallic layers, respectively. Studies of the starting materials and of the interfaces are important if the adhesion mechanism is to be understood. Therefore the initial components—the unheated and heated substrates and the powder particles NiCrAl, Al2O3 and ZrO2-7.25Y2O3—are analyzed. Depth profiles obtained from two coatings St 37/NiCrAl and St 37/Al2O3 show the influence of plasmaspraying on substrate surfaces and sprayed particles. Plasma-spraying mainly causes a decrease of superficial carbon contamination for both coating layers. In the case of St 37/NiCrAl incorporation of carbon in the sprayed layer is observed. The whole layer is almost completely oxidized except for some areas where substrate and particle material are present. It is assumed that these areas are identical with so-called adherence zones.Dedicated to Professor Günther Tölg on the occasion of his 60th birthday 相似文献
