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.
We demonstrated a 100 W class hybrid laser system based on fiber seed laser and two free-space end-pumped Yb:YAG amplifiers capable of delivering record high pulse energy in a rod-type active medium setup operating at room temperature. The achieved output pulse energy was <10 mJ at 10 kHz pulse repetition rate. The output pulses of 1.09 ps duration were close to Fourier transform-limit. The output beam quality remained high (M2 < 1.3) despite being affected by thermally induced stress in the gain medium.
