| 1 | GaSe:AgGaSe_2晶体的光学性能及应用(英文)显示文摘从GaSe:AgGaSe2熔体(质量掺杂浓度为10%)中生长的非线性光学晶体ε-GaSe:Ag晶体(质量掺杂浓度≤0.04%)是一种非中心对称晶体,可用于相位匹配频率转换。Ag的掺入使GaSe晶体的显微硬度提高了30%,从而使其可以在任意方向上进行切割和抛光。本文研究了GaSe:AgGaSe2晶体在可见、中红外及太赫兹波段的光学性能。实验证明:GaSe:AgGaSe2晶体的吸收系数是纯GaSe晶体的2倍,其CO2激光倍频效率是ZnGeP2晶体的1.7倍。 | 古新安 朱韦臻 罗志伟 ANGELUTS A A EVDOKIMOV M G NAZAROV M M SHKURINOV A P ANDREEV Y M LANSKII G V SHAIDUKO A V KOKH K A SVETLICHNYI V A | 2012 | 中国光学2012，5，1： | 5 |

| 6 | Doped GaSe crystals for laser frequency conversion显示文摘In this review,we introduce the current state of the art of the growth technology of pure,lightly doped,and heavily doped(solid solution)nonlinear gallium selenide(GaSe)crystals that are able to generate broadband emission from the near infrared(IR)(0.8 mm)through the mid-and far-IR(terahertz(THz))ranges and further into the millimeter wave(5.64 mm)range.For the first time,we show that appropriate doping is an efficient method controlling a range of the physical properties of GaSe crystals that are responsible for frequency conversion efficiency and exploitation parameters.After appropriate doping,uniform crystals grown by a modified technology with heat field rotation possess up to 3 times lower absorption coefficient in the main transparency window and THz range.Moreover,doping provides the following benefits:raises by up to 5 times the optical damage threshold;almost eliminates two-photon absorption;allows for dispersion control in the THz range independent of the mid-IR dispersion;and enables crystal processing in arbitrary directions due to the strengthened lattice.Finally,doped GaSe demonstrated better usefulness for processing compared with GaSe grown by the conventional technology and up to 15 times higher frequency conversion efficiency. | Jin Guo Ji-Jiang Xie Dian-Jun Li Gui-Long Yang Fei Chen Chun-Rui Wang Lai-Ming Zhang Yury M Andreev Konstantin A Kokh Gregory V Lanskii Valery A Svetlichnyi | 2015 | Light(Science & Applications)2015，4，1： | 1 |

| 14 | AnAll-Regime Lagrange-Projection Like Scheme for the Gas Dynamics Equations on Unstructured Meshes显示文摘We propose an all regime Lagrange-Projection like numerical scheme for the gas dynamics equations.By all regime,we mean that the numerical scheme is able to compute accurate approximate solutions with an under-resolved discretization with respect to the Mach number M,i.e.such that the ratio between the Mach number M and the mesh size or the time step is small with respect to 1.The key idea is to decouple acoustic and transport phenomenon and then alter the numerical flux in the acoustic approximation to obtain a uniform truncation error in term of M.This modified scheme is conservative and endowed with good stability properties with respect to the positivity of the density and the internal energy.A discrete entropy inequality under a condition on the modification is obtained thanks to a reinterpretation of the modified scheme in the Harten Lax and van Leer formalism.A natural extension to multi-dimensional problems discretized over unstructured mesh is proposed.Then a simple and efficient semi implicit scheme is also proposed.The resulting scheme is stable under a CFL condition driven by the(slow)material waves and not by the(fast)acoustic waves and so verifies the all regime property.Numerical evidences are proposed and show the ability of the scheme to deal with tests where the flow regime may vary from low to high Mach values. | Christophe Chalons Mathieu Girardin Samuel Kokh | 2016 | Communications in Computational Physics2016，20，6： | 0 |
| 15 | Combustion Metamorphic Rocks as a Sign of Ancient Mud Volcanoes显示文摘Zones of combustion metamorphism(CM)are frequently associated with oil fields and adjacent bituminous marine sediments.A typical example is the Mottled Zone(MZ)complexes located within carbonate strata at the western margin of the Arabian petroleum province(Israel,Jordan).Being localized upon the eroded surface of Upper Cretaceous stratum, the MZ complexes are composed of brecciated sediments of the underlying Cretaceous sequence uplifted from depths of at least 1.5 km.They | Svetlana Kokh | 2009 | 地学前缘2009，16，S1： | 0 |
