Claim Text:
1. Optical pulse source for providing optical output pulses, comprising: a master oscillator comprising a mode locked fibre oscillator producing optical pulses having an optical pulse frequency; at least one optical fibre amplifier optically coupled to the master oscillator, the at least one optical amplifier including a final optical fibre amplifier; a bulk optic amplifier element optically coupled to the output of the final optical fibre amplifier; a nonlinear optical fibre for nonlinearly producing light, the nonlinear optical fibre optically coupled to the output of the bulk optic amplifier element; an optical pulse compressor optically coupled to the output of the nonlinear optical fibre; and a pulse picker operable to reduce the optical pulse frequency of the optical output pulses to be less than the optical pulse frequency of the optical pulses produced by the master oscillator.
