Abstract
The passively mode-locked, delay-time-controllable Ti:Sapphire laser was demonstrated. Implementation of this technique was done by feedback-controlling the end mirror set integrated with PZT with an optoelectronic phase-locked loop (OEPLL) based phase-shifter circuit. The controlling scheme also benefitted advantages of achieving jitter-reduction, phase-tracking, and delay-time-tuning functions in one circuit module.
