在速率方程和传输方程理论模型的基础上,用重叠积分法和龙格-库塔算法(RK)模拟了重叠因子对共掺Er3+: Yb3+的磷酸盐玻璃光波导激光器的功率输出特性影响。 On the basis of the theoretical model of velocity equation and transmission equation, the overlapped integral method and Runge-Kutta algorithm (RK) were used to simulate the influence of overlap factor on the power output characteristics of the co-doped phosphate glass waveguide laser with Er3 +: Yb3 +.
