摘要：

We report on a compactly packaged Yb-doped fiber-based laser architecture featuring an actively pulse controlled, single-longitudinal-mode seeder and multistage amplifier chain terminated by a "folded" rod-type photonic crystal fiber. In this laser source, stimulated Brillouin scattering (SBS) is the power-limiting factor, but is managed by phase modulating the seeder with a pseudo-random noise signal. Pulse energy/peak power of similar to 2 mJ/1.5 MW at 10 kHz repetition rate are thus obtained within similar to 1.55 ns pulses of peak spectral brightness >20 kW cm(-2) sr(-1) Hz(-1).
