External-cavity feedback can improve the spectral properties of LD or LDB. However  spectrum narrowing of LDB is more difficult than that of LD. Bar curvature (i.e. "smile") produced in the manufacturing process affects the spectrum narrowing greatly. By geometrical optics approach and ORIGIN software  smile which can be corrected by plano-convex cylindrical lens is simulated and the result is in good agreement with experiment. The selection of grating which is also a critical factor of spectrum narrowing will be stated. Finally  an external cavity consisting of fast axis collimator  two plano-convex cylindrical lens and a diffraction grating is used. The scheme is implemented on a 19-element LDB and yields 3-fold reduction in spectral linewidth under the situation that all optical elements in the system which are not optimized. Further  we use a slit in the experiment and analyze the spectrum narrowing of each element in LDB.   (g-2)mu and CP asymmetries in B-d,s(0)-> l(+)l(-) and b -> s gamma in SUSY models 期刊论文  OAI收割 PHYSICS LETTERS B, 2002, 卷号: 538, 期号: 40972, 页码: 301-308 作者:  Huang, CS;  Liao, W;  Huang, CS , Acad Sinica, Inst Theoret Phys, POB 2735, Beijing 100080, Peoples R China.   |  收藏  |  浏览/下载：27/0  |  提交时间：2012/08/29 Supersymmetric Standard Model  Electric-dipole Moment  Supergravity Models  N=1 Supergravity  G-2 Experiment  Violation  Neutron  Decays  Mssm  B->x(s)l(+)l(-)   Muon anomalous magnetic moment in the standard model with two Higgs doublets 期刊论文  OAI收割 PHYSICAL REVIEW D, 2001, 卷号: 64, 期号: 11, 页码: - 作者:  Wu, YL;  Zhou, YF;  Wu, YL , Chinese Acad Sci, Inst Theoret Phys, Beijing 100080, Peoples R China.   |  收藏  |  浏览/下载：23/0  |  提交时间：2012/08/29 Changing Neutral Currents  Electric-dipole Moment  Quark-mass Prediction  Cp Violation  Electroweak Corrections  2-higgs-doublet Model  Hadronic Contributions  Grand Unification  G-2 Experiment  B->s-gamma
