1. A broadband light source, comprising:
a pulse generator for providing a first sequence of first light pulses;
a manipulator configured to generate a burst of second light pulses comprising at least two second light pulses with a time delay in between the at least two second light pulses generated from a single first light pulse to provide a second sequence of second light pulses from the first sequence of first light pulses; and
a nonlinear optical element arranged to receive the second sequence of second light pulses;
where the second light pulses generate a broadband spectrum or a supercontinuum when propagating through the nonlinear optical element,
wherein a ratio between a time duration between successive bursts (Δt3) and intra-pulse temporal spacing between the second light pulses in the burst (Δt2), Δt3/Δt2, is greater than or equal to 5.
