A double-cladd amplifier and an appropriate filter to optimize the system for the amplifier seeding application were employed. This is the highest pulse energy with narrow spectrum at 1018 nm. For a photonic analog-to-digital conversion system operating at 1250 nm, a fiber laser system generating 4 W of femtosecond Cherenkov radiation at that wavelength was built. The characteristics of the Cherenkov radiation were well studied.","abstract_html":"Two novel laser systems for ultrafast applications have been designed and built.
