Sub 30 fs pulses from 2 MHz repetition rate fiber amplifier pumped optical parametric amplifier

We report on a high repetition rate noncollinear optical parametric amplifier system (NOPA) seeded by a cavity dumped Ti:Sapphire oscillator. The pump pulses for parametric amplification are generated via soliton generation in a highly nonlinear photonic crystal fiber with a subsequent fiber-based amplification stage and are therefore synchronized. The system is capable of producing high energy ultra-short pulses at repetition rates up to 2 MHz.
