Active Synchronization and Carrier Phase Locking of Two Separate Mode-Locked Femtosecond Lasers
Two independent mode-locked femtosecond lasers are synchronized to an unprecedented precision. The rms timing jitter between the lasers is 4.3 fs observed within a 160Hz bandwidth over tens of seconds, or 26 fs within a 50 kHz bandwidth. Novel multi-stage phase-locked loops help to preserve this ultrahigh timing resolution while setting on arbitrary delay between the two pulse trains (0–5 ns). ...
متن کاملCarrier-envelope phase control of femtosecond mode-locked lasers and direct optical frequency synthesis
We stabilized the carrier-envelope phase of the pulses emitted by a femtosecond mode-locked laser by using the powerful tools of frequency-domain laser stabilization. We confirmed control of the pulse-to-pulse carrier-envelope phase using temporal cross correlation. This phase stabilization locks the absolute frequencies emitted by the laser, which we used to perform absolute optical frequency ...
متن کاملFrequency comb injection locking of mode locked lasers
The two-frequency problem of synchronization of the pulse train of a passively mode locked soliton laser to an externally injected pulse train is solved in the weak injection regime. The source and target frequency combs are distinguished by the spacing and offset frequency mismatches. Locking diagrams map the domain in the mismatch parameter space where stable locking of the combs is possible....
متن کاملLocking Bandwidth of Actively Mode-Locked Semiconductor Lasers
The locking bandwidth of an actively mode-locked semiconductor laser is a measure of its tolerance to variations in the input drive frequency. At frequencies outside the locking bandwidth, the output pulses from the laser exhibit large amplitude fluctuations and timing jitter. This paper investigates the locking bandwidths of fundamentally driven and harmonically driven high-repetition-rate act...
متن کاملActive Mode Locking With Hybrid Lasers
We present the results of a numerical study of active mode locking with hybrid lasers which contain an inhomogeneously broadened laser medium and a homogeneously broadened laser medium. The spectral, pulse, and gain characteristics of actively mode-locked hybrid lasers and the influence of the unsaturated gain, the saturation power, and the homogeneous linewidth on the pulse coherence and bandw...
