Technique for Highly Stable Active Mode-Locking
- 127 Downloads
We describe a method for producing highly stable active mode-locking of lasers, in which the generated optical pulse train is phase-locked to a RF generator of high spectral purity. This technique results in a dramatic reduction in pulse timing jitter (to as little as ±0.3 ps), which is essential for certain measurement and signal processing applications. We also describe a technique for precise measurement of pulse timing jitter using a monomode optical fibre as a dispersion-free delay line.
