Abstract
It is provided a method for generating a supercontinuum, the method comprising the following steps: a) radiating a carrier laser pulse having a first temporal width onto a first non-linear material; b) at the same time, radiating a second shorter laser pulse having a second temporal width onto the first non-linear material, thereby changing the non-linear properties of the first non-linear material and imprinting a ghost pulse having a third temporal width into the carrier pulse; the second temporal width being at least two times shorter than the first temporal width, and c) radiating the carrier pulse with imprinted ghost pulse onto the first non-linear material or a second non-linear material and generating, by self-phase modulating, a supercontinuum around the center frequency of the carrier pulse.
