Abstract
Ultrashort pulse fiber delivery for Ti:Sapphire lasers is basically restricted to distances below a few meters which is due to the application of dispersion compensating devices that are not capable of managing third and higher order material dispersion. By the use of a fiber delivery concept based on higher order mode fibers ultrashort laser pulses in the 800 nm wavelength range are transmitted over 20 meters without the need for pulse pre-chirping. For the first time a large distance fiber delivery module is demonstrated, revealing its potential for remote THz imaging or spectroscopy using ultrashort laser pulses. Application of the fiber delivery is demonstrated by generating and detecting broadband THz radiation at the fiber output.
