摘要: 为了研究掺Yb3+光纤放大器中自发辐射噪声分布情况,利用离散化的方法求解掺Yb3+)光纤放大器的速率方程,理论研究了不同的抽运方式、端面反射率、抽运功率以及有无滤波等条件下,端面抽运掺Yb3+光纤放大器中自发辐射的功率放大特性.结果表明,不同边界条件下的自发辐射功率差异较大;通过减少光纤端面的菲涅耳反射和利用滤波技术等方法,可有效抑制光纤激光放大器中自发辐射噪声的功率放大.

Abstract: In order to study the distribution of spontaneous noise in a Yb3+ -doped fiber amplifier (YDFA),the power gain characteristics of amplified spontaneous emission under conditions of different pump schemes and power,end surface reflectivity and spectral filter were studied by solving the discrete rate equation.The results show that the power of amplified spontaneous emission is different under different boundary conditions,and that the power amplification of the amplified spontaneous emission can be suppressed effectively by reducing the fiber surface reflectivity and using a properly selected spectral filter.-
