Pulsed fiber laser sources are attractive in terms of simpler delivery to a scanning head, small rugged all-fiber design and good power efficiency. For practical systems both high repetition rate and high energy are required along with single spatial mode output. Increasing in practice the pump power launched in a singlemode fiber is not simple and even then, serious pulse sharpening occurs in high gain fiber amplifier. In order to increase the energy with minimal pulse shaping, we have investigate the use of slightly multimode fibers seeded by a singlemode laser source. We achieved more than 40 (mu) J at 10 kHz for a 10 ns pulse with a good spatial mode and small pulse sharpening. Being able to shape the input pulse, we demonstrate that pre- compensation is possible to maintain uniform peak power over the output pulse.
