Self-referenced 200 MHz octave-spanning Ti : sapphire laser with 50 attosecond carrier-envelope phase jitter

Abstract

Carrier-envelope phase stabilization of a 200MHz octave-panning Ti: sapphire laser without external broadening is demonstrated. The individual comb lines spaced by 200MHz can conveniently be resolved using commercial wavemeters. The accumulated in-loop carrier-envelope phase error ( integrated from 2.5 mHz to 10 MHz) using a broadband analog mixer as phase detector is 0.117 rad, equivalent to 50 attosecond carrier-envelope phase jitter at 800 nm.
