模式锁定是一种非平衡稳态。控制锁模状态的能力可以用来提高性能，以及阐明非平衡物理使用激光作为实验平台。通过在掺镱光纤激光器腔内的傅里叶平面上加入空间光调制器，我们演示了利用光谱脉冲整形直接控制锁模状态。我们证明，我们可以停止和重新启动模式锁定，抑制不稳定性，在模式锁定状态之间诱导可控的可逆和不可逆转换，并在使用短至40 fs的脉冲时执行高级脉冲整形。(C) 2016年美国光学学会
Mode locking is a non-equilibrium steady state. Capability to control mode-locking states can be used to improve performance as well as shed light on non-equilibrium physics using the laser as an experimental platform. We demonstrate direct control of the mode-locking state using spectral pulse shaping by incorporating a spatial light modulator at a Fourier plane inside the cavity of an Yb-doped fiber laser. We show that we can halt and restart mode locking, suppress instabilities, induce controlled reversible and irreversible transitions between mode-locking states, and perform advanced pulse shaping while using pulses as short as 40 fs.
