摘要
利用相位模板，在２４８ｎｍＫｒＦ准分子激光器光束的照射下，在国产高掺锗单模光纤中制作出了中心波长为１５４７ｎｍ，峰值反射率约为１０％，带宽为０．６４ｎｍ的折射率调制光纤布拉格光栅。
The fiber Bragg gratings (FBG) in domestic monomode photosensitive optical fibers were prepared in terms of a 248nm KrF excimer laser and a phase mask. Some FBGs with the reflectivity of 10% and the bandwidth of 0. 6nm were obtained.
