No full textInfluence of stacking fault energy on deformation mechanism and dislocation storage capacity in ultrafine-grained materials
No full textPartial dislocation emission from grain boundaries in metals with medium-to-high stacking fault energies is observed primarily in the grain size range of a few tens of nanometers. Here we report that a reduction in the stacking fault energy permits the emission of partial dislocations from grain boundaries in ultrafine-grained materials with grain sizes significantly larger than 100 nm and this produces twinning. Such twins are effective in increasing the dislocation storage capacity, which may be used to improve the ductilit

No full textEfficient blue light generation from a diode laser pumped Nd:YAG laser
No full textWe report on the efficient intracavity doubling of a 946 nm Nd:YAG laser with an LBO crystal at room temperature. A CW single-ended output power of 103 mW at 473 nm is obtained at a pump power of 2.58 W with an optical conversion efficiency of 4.0%. The overall efficiency is 7.2% if blue light output from both directions is taken into account. To our knowledge, this is the highest efficiency to date for a diode laser pumped compact Nd:YAG blue laser with a simple flat-concave resonator using a bulk nonlinear crystal for intracavity doubling

Fabrication, spectroscopy and laser performance of Nd<sup>3+</sup>-doped single-mode lead-silicate glass-fibres
No full textThe fabrication of a highly efficient Nd3+-doped single-mode fiber laser operating at 1.06km is described. The Nd3+ is introduced by doping Nd2O3 into a multicomponent (flint) lead-silicate glass host, Schott commercial optical glass FV. A fabrication technique for doping rare-earth evenly into commercial optical glasses is demonstrated. Spectroscopic properties relevant to laser operation in the Nd3+-doped lead-silicate glass fibers were measured and the influence of Pb2+ ions on the spectral properties was analyzed. Owing to the long lifetime and large absorption and emission cross-sections of Nd3+ in this lead-silicate glass host, a high-performance Nd3+-doped lead-silicate fibre laser device operating at 1.06µm has been successfully demonstrated

No full textThe elements Na, Mg, Mn, Ca, Sr and Ba in otoliths of southern bluefin tuna Thunnus maccoyii, collected from their feeding ground in the central Indian Ocean and spawning ground between southern Java and north-western Australia were measured by laser-ablation inductively coupled plasma mass spectrometry (LA-ICPMS) and compared among sampling locations and developmental stages. The Na, Mg and Mn to Ca concentration ratios were significantly higher at the larval stage than at the adult stage, and the ratio reached a peak at the first inflection point of the otolith, mean ±s.d. 43·3 ± 4·9 days after hatching and decreased sharply to a low level thereafter. The temporal change of the elements:Ca ratios in the first inflection point corresponded to the life stage transition from larva to juvenile, indicating that the uptake rate of elements from ambient waters was significantly influenced by the ontogenetic change in the fish. The elemental composition at the otolith edge differed significantly in sub-adults on the feeding grounds and adults on the spawning grounds. Thus, the otolith elemental composition can be used as a biological tracer to study the time of the ontogenetic shift and to reconstruct the past migratory environmental history of T. maccoyii. In addition, the elemental composition of the otolith core of the adult was similar between feeding and spawning grounds, indicating that the fish in the Indian Ocean had the same larval origin, which is consistent with the single spawning population hypothesis
