High-energy temporally shaped nanosecond-pulse master-oscillator power amplifier based on ytterbium-doped single-mode microstructured flexible fiber.

We present a versatile master-oscillator power amplifier system at 1053 nm in the few-nanoseconds regime meeting the high-level requirements of high-power laser facility front ends. Thanks to temporal shaping, more than 1.5 mJ pulse energy at 1 kHz with an excellent optical signal-to-noise ratio has been obtained in a single-mode 40 µm core flexible fiber.
