环形腔声光可调谐掺铒光纤激光器调谐范围的研究

Tunable range of acousto-optical tunable erbium-doped fiber ring laser

  • 摘要: 介绍了一种基于声光可调谐滤波器(AOTF)的可调谐掺铒光纤激光器。从掺铒光纤放大器的速率方程和传输方程出发,推导出声光可调谐掺铒光纤激光器的输出公式,理论上解释了该环形腔声光可调谐掺铒光纤激光器调谐范围仅决定于掺铒光纤的增益带宽;并在实验中测得该激光器调谐范围为1526.05nm到1560.63nm,这个区间对应着实验所得掺铒光纤自发辐射谱的增益区间,从而验证了理论推导所得结论。

     

    Abstract: A tunable erbium-doped fiber laser based on acousto-optic tunable filter is introduced. According to the rate equation and transfers equations applicable to the erbium-doped fiber amplifier, the output formula of the acousto-optic tunable erbium-doped fiber laser was deduced. The dependence of the tunable range of acousto-optical tunable erbium-doped fiber ring laser on the amplification bandwidth of erbium-doped fiber amplifier was obtained. In the experiment, the tunable range from 1526.05nm to 1560.63nm was achieved. The experiments show that the tunable range obtained from acousto-optical tunable erbium-doped fiber ring laser is consistent with the theoretically calculated one.
