AbstractAbstract
[en] We propose a method to extend the dynamic stable range of a thermal birefringence compensated two-rod resonator. To get a wide stable range, the resonator configuration with a symmetric confocal type is utilized. We investigate the effect of the distance between two rods of the proposed resonator on the stability and the beam quality.

AbstractAbstract
[en] As the world increases its reliance on nuclear energy, there has been a growth in the demand for new radiation tolerant materials that can withstand the harsh radiation environments of the nuclear industry. Ceramics, due to their outstanding physio-chemical properties, are extensively used in this field. The oxide ceramics employed in the hostile nuclear reactor environment are subjected to various high (fission fragments) and low (alpha recoils) energetic particles and are hence prone to undesirable radiation damages. It has been recently discovered that these materials in nano-dimension exhibits enhanced radiation tolerance as compared to their bulk counterparts. However, going to a highly nano-crystalline state might not be advantageous as the intense 'thermal spike effect' involved in nano-materials may lead to extensive damage. Thus, the radiation stability of nano-materials is still a matter of debate

AbstractAbstract
[en] The authors fabricated micron-scale, oxygen deficient YBa2Cu3O7-x photoconductors in an otherwise superconducting thin film by scanning focused laser beam across a narrow bridge in the superconducting film while under vacuum. In the oxygen deficient region they observe semiconducting transport properties and a photoconducting response. In this work they present results on the temporal photo-response of this superconducting-semiconducting-superconducting structure and discuss the current understanding of the photoconducting mechanism

AbstractAbstract
[en] Maps of the dynamics of an optically injected solid-state Nd:YVO4 laser are presented. Experimental maps showing different dynamical regions are generated automatically from measured intensity time series by plotting the maxima of intensity. Corresponding numerical maps and a bifurcation diagram are calculated with a rate equation model of an injected class B laser. Intensity time series inside different regions in the maps are examined. The experimental and numerical maps are shown to be in good agreement with each other if the linewidth enhancement factor α is used as a fitting parameter in the model. As a result, experimental estimates for an effective α are given for a Nd:YVO4 laser. The effects of noise on the dynamics are also discussed

AbstractAbstract
[en] Attempts were made at separating Nd-Y pair by fractional precipitation of terephthalates in the presence of complexing agent (EDTA). The enrichment of fractions varied and depended on the quantity of the complexing agent and composition of the solution used. The first fractions were found to be enriched with neodymium, whereas the final fractions with yttrium. Several repetitions of that procedure permitted to isolate relatively pure neodymium and yttrium. (author)
