摘要
提出了一种新颖的单纵模、单偏振的可调谐掺铒光纤激光器结构。使用准共线型声光可调谐滤波器作为调谐元件。利用饱和吸收效应在未泵浦低掺铒光纤中形成自写入瞬态光栅,用以压窄输出激光的线宽,并且有效地防止跳模。理论计算表明:当泵浦功率为100mW时,激光器的输出功率可达5.5mW,输出线宽在10-4nm量级。这些数据对后续的实验研究有指导作用。
A novel configuration of tunable single\|longitudinal and single\|polarization erbium\|doped fiber laser is presented, while two stages of quasi\|collinear acoustooptical tunable filters(AOTFs) are used as the tuning elements. An unpumped Er3+\|doped fiber(low dopant) is used to narrow the linewidth and eliminate mode hopping. The theoretical calculation shows the output power is 5.5 mW and the linewidth can reach 10-4 nm level when the pump power is at 100 mW. All these data are significant for the oncoming experimental study.
