Abstract

We present our recent developments in fiber-based technologies that enable unique high energy and average power ultrafast laser operation regimes. A patented all-fiber front-end incorporates dual-wavelength pulse generation of signal and pump pulses for high intensity OPCPA systems [1]. A newly introduced all-in-fiber active fiber loop (AFL) technology allows to form bursts of ultrashort seed pulses with any desired pulse repetition rate and any number of pulses in a burst with identical intra-burst pulse separation. Furthermore, the AFL introduces the ability to build systems with tunable pulse durations from a few hundred femtoseconds to picoseconds and even up to the nanosecond range. Novel fiber technologies were implemented into a high energy pump laser for a few-cycle mid-IR OPCPA system to produce unprecedented performance and output parameters for high-field science applications.
