abstract = {We recently commissioned the Next GenerAtion Photocathode
Laser system (NEPAL) in Hamburg’s XFEL facilities (FLASH
and EuXFEL) and at DESY’s Photoinjector Test Facility
(PITZ). The system delivers deep UV pulse trains up to 1 ms
long at repetition rates as high as 4.5 MHz, with temporal
and spatial shaping capabilities and individual amplitude
control for bunch charge manipulation. The shaping features
enable the generation of exceptionally low emittance
electron beams, essential for extending the EuXFEL X-ray
photon energy beyond 25 keV and for future high duty cycle
upgrades. Temporal shaping is achieved through a
high-resolution spatial light modulator in the near-infrared
driver laser, allowing precise spectral amplitude and phase
control of UV pulses. We will present advanced control
schemes that pre-compensate for laser nonlinearities and
initial experimental results at EuXFEL. We generated UV
flat-top pulse profiles with durations ranging from 10ps to
20ps and successfully transferred them onto the electron
beam. This achievement represents a significant step toward
emittance optimization at EuXFEL and will expand the
facility's operational energy range in the near future.},
