Description
LCLS-II is advancing attosecond X-ray science by optimizing electron beam generation at the photoinjector through tailored UV laser pulses. We introduce a novel method combining IR spectral shaping and dispersion-controlled nonlinear upconversion to produce customizable UV profiles (e.g., flattop, multi-spike). Preliminary LCLS-II experiments confirm these modulations effectively perturb electron bunches downstream. This approach, integrated into a start-to-end simulation framework, paves the way for programmable, application-specific X-ray pulse generation, enabling end-to-end optimization of XFEL performance.
