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.   Local linear additive quantile regression 期刊论文  OAI收割 SCANDINAVIAN JOURNAL OF STATISTICS, 2004, 卷号: 31, 期号: 3, 页码: 333-346 作者:  Yu, KM;  Lu, ZD   |  收藏  |  浏览/下载：20/0  |  提交时间：2018/07/30 additive models  average derivative  backfitting algorithm  bandwidth selection  local linear fitting  quantile regression   Deconvolution kernel estimator for mean transformation with ordinary smooth error 期刊论文  OAI收割 STATISTICS & PROBABILITY LETTERS, 2003, 卷号: 61, 期号: 4, 页码: 337-346 作者:  Qin, HZ;  Feng, SY   |  收藏  |  浏览/下载：16/0  |  提交时间：2018/07/30 measurement error  bandwidth selection  super population  rates of convergence   IMPROVEMENT OF SELECTIVITY WITH NUMERICAL DERIVATIVE TECHNIQUES IN INDUCTIVELY COUPLED PLASMA ATOMIC EMISSION-SPECTROMETRY 期刊论文  OAI收割 spectrochimica acta part b-atomic spectroscopy, 1991, 卷号: 46, 期号: 6-7, 页码: 953-965 YANG JF; PIAO ZX; ZENG XJ 收藏  |  浏览/下载：30/0  |  提交时间：2011/03/03 SPECTRAL INTERFERENCES  DETECTION LIMIT  LINE SELECTION  HIGH-PURITY  ICP-AES  RESOLUTION  BANDWIDTH  ELEMENTS  SYSTEM  WIDTHS
