Abstract
A source of femtosecond optical pulses comprises a seed pulse source arranged to generate seed pulses; an optical amplifier downstream of the seed pulse source, the optical amplifier having a gain bandwidth; a nonlinear optical element downstream of the amplifier, the optical element spectrally broadening optical pulses via a non linear process to have a spectral bandwidth that exceeds the gain bandwidth of the optical amplifier; and a pulse compressor downstream of the nonlinear optical element and arranged to reduce the temporal duration of optical pulses so as to provide output optical pulses having a femtoseconds time duration.
