【摘要】 在指出传统的锁模方程中的缺陷之后,利用自洽模型,重新推导出适用于同步泵浦染料激光器的锁模方程;从此方程出发,只需将其中的增益项G(t)对时间t展开到二阶,便能求出光脉冲宽度τ,强度I_o等量的较精确的解析解,这些结果与实验事实相符,并能解释原方程的二阶解所无法解释的现象。更多还原

【Abstract】 A new mode-locked equation suitable for synchronously pumped dye lasers is presented, after the drawbacks in the conventional equation are pointed out. The analytical expressions for pulsewidth τ and pulse-intensity l₀ are obtained by expanding the gain G（t） to second order of t only. The theoretical analyses are well consistent with experiments and can interpret some experimental phenomena which can not be explained by the second order solution of the original equation.更多还原
