Optimization of beat frequency signal between synchronized Ti:sapphire and Cr:forsterite lasers

摘要

We measured relative carrier-envelope phase slipping between synchronized femtosecond Ti:sapphire and Cr:forsterile lasers. Beat signals with signal-to-noise ratio of high as 40 dB were obtained by maximized correlating doubled Ti:sapphire and tripled Cr:forsterite laser pulses.
