Zusammenfassung:Radiation source assembly and method for generating broadband radiation by spectral broadening. The radiation source assembly comprises a pump assembly configured to provide broadband input radiation. The pump assembly comprises a pump source configured to provide first radiation at a pump wavelength, and a broadband assembly configured to provide second radiation comprising a continuous wavelength range, wherein the first radiation and the second radiation form the broadband input radiation. The radiation source assembly further comprises an optical fibre configured to receive the broadband input radiation. The optical fibre comprises a core configured along at least a part of the length of the fibre to guide the received broadband input radiation during propagation through the fibre, so as to generate broadband radiation by spectral broadening to be output by the fibre.
