摘要
本文用半经典理论讨论了光纤激光器中光场的运动方程及零级和一级近似解.理论计算表明,单模光纤的芯区平均稳态光强为普通激光器理论值的1.5倍,线性增益系数为1.12倍,饱和系数为0.76倍.
In this paper, we introduced the equations of the propagation of light in the fiber lasers, and received the analytic solution of the equation under zero-order and first-order perturbations. Numerical calculation shows that the average intensity, gain and saturation coefficients of light in the core of the fibers will be 1.5, 1.12 and 0. 76 times as much as those of the general lasers respectively.
