1. A radiation source comprising:
a modulator configured to modulate pump laser radiation comprising a train of radiation pulses to provide modulated pump laser radiation, the modulation being such to selectively provide one or more bursts of the pulses, the one or more bursts having a temporal delay longer than a temporal delay between successive individual pump pulses; and
a hollow-core photonic crystal fiber configured to receive the modulated pump laser radiation having the one or more bursts and excite a working medium contained within the hollow-core photonic crystal fiber so as to generate broadband radiation.
