摘要： An optical pulse source comprising a DPSS pump laser, a photonic crystal fiber (PCF), and acousto-optic modulator (AOM) gating device is disclosed. The pump pulses are coupled through lenses to the AOM gating device, which is synchronized to the pump laser and is operable to gate the pump pulses to a reduced repetition rate Rr=Rf/N, where Rf is the pump laser fundamental frequency. The pulses from the AOM are injected via optics into the PCF. Propagation through the PCF causes the pulses to broaden spectrally to produce optical supercontinuum pulses. An optical pulse source that further includes an acousto-optical tunable filter (AOTF) operable to convert the optical supercontinuum pulses into wavelength variable output pulses is also provided. A method of scaling the energy of the optical supercontinuum pulses is also disclosed.

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