Abstract:
A system for an extreme ultraviolet (EUV) light source includes a light-generation system configured to emit one or more light beams onto a beam path; one or more optical amplifiers, each of the one or more amplifiers including a gain medium on the beam path, each gain medium being configured to amplify the one or more light beams to produce one or more amplified light beams; and one or more diffractive optical elements on the beam path, where each of the one or more diffractive optical elements has a plurality of focal lengths, and each focal length of the diffractive optical element is associated with a particular polarization state.

Claim (Index 20):
A method comprising:\n emitting a forward-going light beam onto a beam path, the forward-going light beam having a first polarization state and propagating on the beam path in a first direction; modifying a wavefront of the forward-going light beam by interacting the light beam with a diffractive optical element, wherein the diffractive optical element is configured to cause a plurality of wavefront modifications to an incident light beam, and each of the wavefront modifications is associated with a polarization state of the incident light beam; and modifying a wavefront of a reflection of the forward-going light beam by interacting the reflection with the diffractive optical element, the diffractive optical element modifying the wavefront of the incident light beam and the wavefront of the reflection differently.
