Abstract:
1. A laser system for generating laser output light having a nominal UV-DUV output frequency, the laser system comprising: a fiber-based fundamental light source for generating fundamental light at a nominal fundamental frequency including: one or more seed lasers including means for generating seed light having an initial peak power and an initial spectral bandwidth, and for transmitting the seed light along an optical path; one or more amplifiers disposed in the optical path and including means for amplifying the seed light generated by said one or more seed lasers such that amplified light output from the one or more amplifiers has a fundamental peak power that is substantially higher than the initial peak power; and one or more nonlinear chirp elements disposed in the optical path for combining one of the seed light and the amplified light with one or more nonlinear chirps; and a frequency conversion module including means for converting said fundamental light from said nominal fundamental frequency to said laser output light L having said nominal output frequency, wherein the one or more amplifiers have inherent Self Phase Modulation (SPM) characteristics, and
