Abstract :
We report on a novel approach toward generating high peak powers in passively mode-locked fiber lasers. By appropriate design the fiber´s mode area is increased by a factor of /spl sim/30 compared to standard fiber. This increased area effectively decreases the nonlinearity thus, increasing the power necessary to form stable soliton-like pulses.
