Abstract
An LSP broadband light source is disclosed. The LSP broadband light source may include a pump source configured to generate a pump beam and one or more collimating optical elements configured to collimate the pump beam into a collimated pump beam. The light source may include one or more focusing optical elements and a beamsplitter located at a conjugate plane between the one or more collimating optical elements and the one or more focusing optical elements. The light source may include a gas containment structure. The beamsplitter may be configured to split the collimated pump beam into a set of pump beamlets, wherein the one or more focusing optical elements are configured to focus the set of pump beamlets to a set of focus positions within the gas to generate multiple plasma regions at the different focus positions.
