Abstract :
In this paper, we report on the investigation of energy scaling in modelocked fiber oscillators. And the generation of microjoule pulses is demonstrated in a low nonlinearity large mode area (LMA) photonic crystal fiber (PCF) oscillator without dispersion compensation. We applied the chirped pulse concept to the LMA-PCF laser by incorporation of a positive dispersive element with negligible nonlinearity directly in front of the gain fiber, in order to achieve further energy and peak power scaling.
