Ultrafast Lasers for Generation of Electron Sources and Precision Microfabrication

A centralized femtosecond laser system will be described, powering multiple experimental platforms—including an RF linac, microfabrication and microscopy stations, and a THz generation setup. The lecture focuses on ultrashort-pulse laser applications in RF photoinjectors, highlighting how laser parameters affect photoemission, bunch shaping, and synchronization. Tunable-delay split pulse pairs are presented as a method for structuring electron bunches, followed by a discussion on microfabrication techniques for developing beam-shaping components.
