紫外有机薄膜激光器

已经证实，由有机化合物组成的激光活性固体材料，在整个可见光谱区具有产生激光的能力。它们的潜力来自内在的优点，如有机化合物的调谐范围宽，有多种化合物可用，易于做工程实际装置。缺点包括实现直接电激励困难，以及缺少在紫外区发射的化合物。     

应用TEXTIO和MATLAB进行复杂数字系统仿真

在基于FPGA的复杂数字系统的仿真测试中,设计者常常面临各种挑战.以数字图像处理系统的仿真为例,如果采用完备性仿真测试方法,那么测试矢量的数量将是非常巨大的;如果采用常规方法,不仅效率不高,而且可能无法达到仿真测试的目的.针对这个难题,提出一种进行仿真测试的新方法,该方法应用TEXTIO和MATLAB来辅助仿真测试过程,使问题得到较好的解决.以电视图像实时多目标捕获单元的仿真测试为例,全面、细致地讨论这种新方法.     

有效的激励机制是电信企业留住人才的重要保障

中国加入VTO后，国内电信市场已分阶段地逐步开放，外资将逐渐涉足中国电信市场，中国电信业将面临一场新的革命。由于国内的人力资源成本相对国外低很多，外资进入中国以后，将大力推进人才的本地化战略，那些具有较高的业务水平和丰富工作经验管理、技术人才，必然成为国外大公司所招聘人才的主要目标。因此，电信企业应该形成以留住优秀人才为目的合理的激励机制，避免企业人才的流失。

Theoretical Research on a Kind of Quantum Left-handed Metamaterial

Recently, research on left-handed materials （LHMs） has attracted considerable attentions. The LHMs are a kind of metameterial which have negative permittivity and negative permeability, which lead to negative refractive index in a frequency range. The LHMs that have been available so far are in the microwave range and are usually composed of classical particles, such as split-ring resonators. Some quantum phenomena such as spontaneous emission of atoms in the LHMs which are considered to be ＇classical background＇ have also been investigated. Many potential applications of LHMs have been proposed, such as superlenses which, in principle, can achieve arbitrary subwavelength resolution.     

A Class of Two-mode Nonclassical State via Generalize Super Positions of Two-mode Coherent States

A new method is introduced to generate a elliptical hollow beam inside a cavity. Using a matrix eigenvalue method, the laser resonator with optical diffraction elements is theoretically analyzed and simulated. A elliptical hollow beam of good quality is realized experimentally. The interaction between linearly polarized elliptical hollow beam and a two-level atom is investigated theoretically. Although the linearly polarized elliptical hollow beam does not carry angular momentum, it can produce very high torque. The atoms initially at rest and located at off-beam- axis positions will rotate under the drive of the torque of the beam. The atomic motion trajectory in the field of elliptical hollow beam has been demonstrated. The study shows that the elliptical hollow beam might be a useful tool in the study of vortex property of Bose-Einstein condensate or ultra cold atom media.
