Abstract: A method of patterning lithographic substrates, the method comprising using a free electron laser (FEL) to generate EUV radiation and delivering the EUV radiation to a lithographic apparatus (LA) which projects the EUV radiation onto lithographic substrates, wherein the method further comprises reducing fluctuations in the power of EUV radiation delivered to the lithographic substrates by using a feedback-based control loop (CT) to monitor the free electron laser and adjust operation of the free electron laser accordingly.
