摘要:
A method of generating light pulses including pumping laser pulses with a pump laser source, coupling the laser pulses into a pulse guiding medium having an anomalous group-velocity dispersion and a Kerr nonlinearity, and propagating the laser pulses along the pulse guiding medium, wherein soliton-shaped light pulses are formed from the laser pulses within the pulse guiding medium and, resulting from a photoionization of the pulse guiding medium by the light pulses, the light pulses are subjected to a frequency, wherein the method further includes setting the pump laser source and the pulse guiding medium such that the light pulses are fundamental soliton light pulses propagating in the pulse guiding medium, wherein the group-velocity dispersion of the pulse guiding medium being selected such that a ratio of the dispersion and the Kerr nonlinearity decreases with increasing frequency and the fundamental soliton light pulses are compressed with the frequency shift.
