| 摘 要： | 利用785 nm激光二极管作为泵浦源,对长度为4.5 m,纤芯直径为20μm,内包层截面为D形的掺铥双包层光纤进行可调谐实验研究.通过使用闪耀光栅作为选频元件,利用后向Littrow结构,获得波长在2μm附近最大105 nm范围内的可调谐输出,且在可调谐范围内,各激光光谱线宽均约2.2 nm.结果表明,可调谐波长范围除与光纤荧光谱有关外,还与闪耀光栅特性参数直接相关.

| Abstract: | A study on tunable thulium-doped fiber laser pumped by a 785 nm LD was proposed.The Tm fiber was 4.5 m long with core diameter of 20 m and D-shaped cross section of the inner cladding.A back-Littrow configuration was adopted with a blazed grating as a frequency selecting component.The maximum tunable range reached 105 nm from 1 938 nm to 2 043 nm with launched pump power of9.46 W,and the line width of each laser spectrum was about 2.2 nm in the tunable range.Analysis indicated that the tunable range was not... |
