锁模激光器中的暗孤子

Dark solitons in mode-locked lasers

摘要:

利用功率-能量饱和模型研究了锁模激光器中暗孤子的形成。发现一般的初始条件在适当的条件下也能演化成暗孤子,实验观测也满足了这一条件。得到的脉冲很好地近似为未微扰非线性薛定谔方程的暗孤子。值得注意的是,相同的框架也描述了异常和正常色散激光器中的明亮脉冲。

英文摘要:

Dark soliton formation in mode-locked lasers is investigated by means of a power-energy saturation model which incorporates gain and filtering saturated with energy, and loss saturated with power. It is found that general initial conditions evolve into dark solitons under appropriate requirements also met in the experimental observations. The resulting pulses are well approximated by dark solitons of the unperturbed nonlinear Schrödinger equation. Notably, the same framework also describes bright pulses in anomalous and normally dispersive lasers.
