摘要：
This Letter introduces a novel, to the best of our knowledge, method for achieving mode-locking and synchronization of mode -locked output pulses from two lasers. The proposed technique leverages parametric gain from difference frequency generation. Specifically, a Nd:YAG laser is mode -locked by single -pass mode -locked pulses from a mode -locked Ti:sapphire laser using an intracavity nonlinear crystal. When the continuous-wave laser is not actively pumped, the system functions as a synchronously pumped optical parametric oscillator. This novel approach has the potential to enable new devices, especially for pump-probe applications or for generation of mode -locked pulses in spectral regions where conventional mode -locked devices are typically not available.
