PD08–Supercontinuum generation with superior intrapulsecoherence in dispersion-tailored waveguides

Intrapulse coherence is an important performance metric for applications of supercontinua, including precision frequency metrology and attosecond science. These applications require a stable carrier-envelope phase, which is usually measured by f–2f interferometry. Here, the potential for superior intrapulse coherence with 100 and 400-fs input pulses is studied, exploiting different dispersion profiles. The simulation results in this study provide a guideline for coherent spectral broadening, which can be exploited to minimize fluctuations of the carrierenvelope phase.
