摘要： A source of femtosecond laser pulses (50) comprising a 980nm picosecond seed pulse source (12), a Ytterbium (Yb) doped fibre amplifier (14) operating in the three-level regime, a passive air-clad fibre (52) and a pulse compressor (16). The seed pulses are spectrally broadened due to self phase modulation (SPM) in the air-clad Yb doped fibre (18) and further broadened due to SPM in the passive core of the passive air-clad fibre (52), to produce sufficient spectral broadening to allow the pulses to be compressed in the dispersion compensator (16) into femtosecond pulses.The Yb doped fibre may have a phosphosilicate host composition in order to mitigate photodarkening.
