    "abstract": "A tapered semiconductor amplifier is injection seeded by a femtosecond\noptical frequency comb at 780 nm from a mode-locked Ti:sapphire laser. Energy\ngains over 17 dB (12 dB) are obtained for 1 mW (20 mW) of average input power\nwhen the input pulses are stretched into the picosecond range. A spectral\nwindow of supercontinuum light generated in a photonic fiber has also been\namplified. Interferometric measurements show sub-hertz linewidths for a\nheterodyne beat between the input and amplified comb components, yielding no\ndetectable phase-noise degradation under amplification. These amplifiers can be\nused to boost the infrared power in f-to-2f interferometers used to determine\nthe carrier-to-envelope offset frequency, with clear advantages for\nstabilization of octave-spanning femtosecond lasers and other supercontinuum\nlight sources with very limited power in the infrared.",
