Description
Optimized photoinjectors are crucial for successful linac-based, free electron laser operation. Beam dynamics simulations have shown that ellipsoidal photocathode laser pulses result in the lowest electron beam emittance. Therefore, in collaboration with the Institute of Applied Physics (Nizhny Novgorod, Russia) and the Joint Institute of Nuclear Research (Dubna, Russia), a prototype laser system capable of generating quasi-ellipsoidal laser pulses was developed and installed at the Photo Injector Test facility at DESY, Zeuthen (PITZ).
The pulse shaping was realized through chirped pulse frequency modulation in the Fourier plane with spatial light modulators, and is characterized by both auto- and cross-correlation measurements in the infrared and ultraviolet.
In this contribution an overview, preliminary results, and revisions of the prototype quasi-ellipoidal laser, and the subsequent re-design, are presented.
