Coupled cavity modelocking of a Nd:YAG laser using second harmonic generation
At Conference on Lasers and Electro-Optics (CLEO '89), United States.
24 - 28 Apr 1989.
Recently it has been demonstrated that intracavity second harmonic generation (SHG) In a Nd:YAG laser can lead to mode locking with pulse durations of ~ 100 ps at 532 nm. Other work has shown that nonlinear processes in an external coupled cavity can effectively mode lock a laser. These two mechanisms are combined to mode lock a Nd:YAG laser using SHG as the nonlinearity
