摘要
采用有限差分方法对双波长飞秒激光器的锁模方程进行了数值分析, 得到了不同参数下交叉锁模脉冲的数值解。结果表明, 在双光束谐振腔内, 由于自相位调制、群速色散、交叉耦合、增益放大以及损耗调制的作用, 在一定条件下, 激光器能够从连续运转状态发展到锁模状态,
Num erical m ethod is used to study dynam ic characteristics of dual w avelengthfem tosecond lasers and finite difference is used to solve cross m ode locking equations. Theresults show that tw o trains of m ode locking pulses interact in tw o beam laser cavity and un der specific condition, i.e., group velocity dispersion, self phase m odulation, cross cou pling, gain am plification and loss are balanced, laser can be cross m ode locked, so crossm ode locking fem tosecond pulses can be generated.
