Abstract: A radiation source includes an initial source, a non-linear optical frequency converter, a conversion detector and a controller. The controller is arranged such that in a first mode of operation, the controller generates the conversion control signal in dependence on the conversion measurement signal such that the resonance frequency is controlled to follow the initial centre frequency. The controller is selectably switchable between the first mode of operation and a second mode of operation. In the second operating mode the power of the converted radiation is controlled such that either the power of the converted radiation has a smaller relative variation over time than the power of the initial radiation in the beam direction in front of the coupling mirror or the power of the initial radiation in the beam direction behind the coupling mirror has a smaller relative variation over time than the power of the initial radiation in the beam direction in front of the coupling mirror.
