Abstract:
A mode locked fiber laser system is arranged to have a lasing bandwidth and having a linear cavity, the cavity including a gain medium, a saturable absorber having a saturation power, and a filter having a spectral response, wherein the mode locked fiber laser system is arranged so that substantial CW mode locked operation is obtainable with less than 3 times the saturation fluence impinging on the saturable absorber.
