| 摘 要： | 单模光纤激光器在光通讯和光传感中具有广阔的应用前景。分析了复合腔光纤激光器的构成及单模的实现特点,提出了一种新颖的光纤复合环形腔激光器结构,并对其进行了实验研究。该激光器使用了波长为980nm的半导体激光器作为泵浦源。三个腔长均为2m,彼此之间的腔长差为1～2mm的光纤环形滤波器与主谐振腔构成复合腔。此激光器在波长为1562nm处得到了线宽小于0.1nm的单模激光输出,输出的光功率可达到1mW。该激光器的阈值为5mW,斜率效率为4%。

| Abstract: | Single-mode fiber laser is very important light sources for optical sensing and optical communication. The configuration of compound-ring fiber laser and the mechanism to achieve single-mode laser output are analyzed. A novel fiber ring laser's configuration is proposed and experimental study on it has been done. The laser is pumped by 980nm laser-diode. Three 2- meter-long fiber-ring resonator filter is inserted into the main cavity, this compound-ring resonator ensures single-longitudinal-mode laser oscillation. The output spectral bandwidth is measured less than 0.1nm at 1562nm. The maximum output power can reach 1mW. The laser has a threshold of 5mW and a slope efficiency is of 4%. |
