Abstract
This paper presents a dual-cavity mode-locked laser, which is able to simultaneously output two optical pulses with different wavelengths and frequency. In this dual-cavity configuration, one cavity works as a regenerative mode-locked laser and outputs signal with a fundamental repetition frequency, the other one acts as an active mode-locked laser and generates signal with subharmonic or harmonic frequency by fine tuning the cavity length. In experimental demonstration, 5GHz signal from regenerative mode-locked cavity and 2.5/ 5/ 10/ 15/ 20GHz signal from active mode-locked cavity are simultaneously obtained. Additionally, signals in active mode-locked cavity get further super-mode suppression.
