[en] Gradient refractive index antireflection films are produced by a chemical etch/leach process applied to phase separable glass ARG 2, optical quality, of which would be easily obtained. The reflectance (one surface) is effectively reduced from 4.05% to lower than 0.5% in the wavelength regime 0.4 to 1.4μ. This laser damage threshold is 11.5 +- 1.5 J/cm², indicating that ARG 2 is available for the optical component in high power laser system such as spatial filter lenses

[en] This paper reports a channel waveguide was fabricated in a Nd³⁺ doped laser glass with the ion exchange method and its lasting characteristics are demonstrated. The device was end-fire pumped by a diode-laser operating at 802 nm. The CW lasing was observed at 1054 nm and maximum output power was higher than 150 mW

[en] There are some theories about the Paleotethys event during the Paleozoic that have been proposed by geologists (Metcalfe, 2006). Some scientist offered some pieces of evidence about the northern margin of Gondwana (Zhu et al., 2010). The Paleotethys Ocean and Hercynian orogenic report first in Iran, have been Offered from the Morrow and Misho Mountain (Eftekharnejad, 1981). Misho Mountains is located between the north and south Misho faults and cause the formation of a positive flower structure (Moayyed and Hossainzade, 2011). There is theory about Misho southern fault as the best candidate of the Paleotethys suture zone (Moayyed and Hossainzade, 2011). Geochemistry and Sr –Nd isotopic data of the A2 granitic and Synite rocks of the East Misho, indicate that the magmatism post collision has occurred in the active continental margin by extensional zones of the following the closure of the Paleotethys (Ahankoub, 2012). Granite and syenite rocks have been cut by mafic dikes. Mafic dikes are often formed in extensional tectonic settings related to mantle plume or continental break –up (Zhu et al., 2009). In this paper, we use the geochemistry and Nd-Sr isotope data to determined petrogenesis, tectono-magmatic setting and age of Misho mafic dikes.
