Hybrid inno-zigzag slab amplifier delivers gain for 1 kHz high-energy picosecond pulses.

We report a novel, to the best of our knowledge, inno-zigzag slab laser amplifier that innovatively combines features of innoslab and zigzag slab amplifiers. Operating at 1 kHz repetition rate, this architecture amplifies 300 ps pulses from 0.4 mJ to 57.

1 kHz, 70 mJ, high-energy hundred-picosecond fiber-solid-state hybrid laser amplification.

We have demonstrated a 1 µm fiber-solid-state hybrid high-energy laser in the hundred-picosecond range. Operating at a repetition rate of 1 kHz, the output energy was 71.1 mJ with a pulse duration of 63.

315 mJ, 430 ps, high-energy laser at 1 kHz repetition rate based on a zig-zag slab amplifier.

We have demonstrated a 1 µm high-energy zig-zag slab laser amplifier. Operating at a repetition rate of 1 kHz, the output energy was 315 mJ with a pulse duration of 430 ps. A two-stage end-pumped Nd:YVO laser was used to pre-amplify the seed energy (320 µJ) of the passively Q-switched microchip laser to 6.
