Abstract
We report on the fiber-based amplification of a flash lamp pumpedQ-switched Nd:YAG laser. At a repetition rate of 10 Hz and spectrum widthof 0.1 nm, an output single pulse energy of up to 12 mJ is generated in a95 µm core Yb-doped large mode area fiber with a seed pulse energy of 0.75 mJ and pulseduration of 11 ns. No stimulated Brillouin scattering, stimulated Raman scattering orsaturation are observed. Furthermore, higher pulse energies will be achieved with higherpump powers.
