| 摘 要： | 选用介质膜作谐振腔镜,光纤激光器就缺乏有效的选频机制,使得输出激光线宽较宽,纵模频率和输出功率不够稳定；而光纤光栅作为激光器的谐振腔镜,可以得到稳定的窄线宽激光输出.通过对光纤光栅的形成机理和布拉格光栅选频原理分析,得到双布拉格光纤光栅线型谐振腔的理论.光纤光栅谐振腔的长度与光纤光栅中心波长满足S=(2m-1)λmax... |

| Abstract: | If used dielectric film as cavity mirrors,the output laser linewidth of fiber laser would be wide,moreover the longitudinal mode frequency and output power are not stable enough because of the lack of effective mechanisms for frequency selection.Using fiber grating as laser cavity mirrors,we can acquire stable,narrow linewidth laser output.Through the analysis of optical fiber bragg grating formation mechanism and the frequency selection principle of bragg grating,dual bragg fiber grating linear cavity theo... |
