Classification: CPC G  H | IPC G  H

Claim 13:
14. A method, comprising:
providing, by a controller and to a primary laser source associated with an extreme ultraviolet (EUV) radiation source, a first signal to cause the primary laser source to generate a first plurality of laser beams,
wherein the first plurality of laser beams are to be used to generate, from a first plurality of droplets of a target material, a plasma within a vessel of the EUV radiation source;

providing, by the controller and to the primary laser source, a second signal to deactivate the primary laser source after the first plurality of laser beams are generated; and
providing, by the controller and to an auxiliary laser source associated with the EUV radiation source, a third signal to cause the auxiliary laser source to generate a second plurality of laser beams to generate the plasma from a second plurality of droplets of the target material,
wherein the third signal is to cause the auxiliary laser source to generate the second plurality of laser beams at least one of:
concurrently with the primary laser source generating a subset of the first plurality of laser beams, or
after the primary laser source finishes generating the first plurality of laser beams.
