Self-pulsing in a large mode area, end-pumped, double-clad ytterbium-doped fiber laser

The characteristics of self-pulsing in a large mode area, end-pumped, double-clad Yb-doped fiber laser are presented. The laser operates in a self-pulsing regime either by using one or two perpendicularly cleaved ends as the feedback mirrors while it transforms in a broadband amplified spontaneous emission source when both ends are angle cleaved. In the pulsed regime, up to 2 microseconds FWHM pulse widths and repetition rates of the order of hundreds of kHz are generated.
