Abstract
We report the first higher-order-mode fiber with anomalous
dispersion at 800nm and demonstrate its potential in femtosecond pulse
delivery for Ti:Sapphire femtosecond lasers. We obtain 125fs pulses after
propagating a distance of 3.6 meters in solid-silica fiber. The pulses could
be further compressed in a quartz rod to nearly chirp-free 110fs pulses.
Femtosecond pulse delivery is achieved by launching the laser output directly into the delivery fiber without any pre-chirping of the input pulse. The demonstrated pulse delivery scheme suggests scaling to >20meters for pulse delivery in harsh environments not suited for oscillator operation or in applications that require long distance flexibility.
