Abstract:
1. A fiber-based fundamental light source for generating fundamental light at a nominal fundamental frequency a laser system, the fiber-based fundamental light source comprising: 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 and including means for modifying one of the seed light and the amplified light to include one or more nonlinear chirps that compensate for Self Phase Modulation (SPM) characteristics of the one or more amplifiers, wherein each of said one or more nonlinear chirp elements comprises one of a Bragg grating, a fiber Bragg grating and an electro-optic modulator, and wherein said one or more nonlinear chirp elements comprise means for generating said nonlinear pre-chirp with a nonlinearity on the order of x
