LASER-DRIVEN METAL PHOTOCATHODES FOR PICOSECOND ELECTRON AND X-RAY PULSE GENERATION

Linear photoemission from pure metal surfaces has been studied using the fourth (263 nm) and fifth (211 nm) harmonic of a Nd:YLF laser-regenerative amplifier system for the purpose of generating short (< 70 ps), intense electron pulses. Capacitive charge limitations for the pulsed mode of operati...

Description
Summary:Linear photoemission from pure metal surfaces has been studied using the fourth (263 nm) and fifth (211 nm) harmonic of a Nd:YLF laser-regenerative amplifier system for the purpose of generating short (< 70 ps), intense electron pulses. Capacitive charge limitations for the pulsed mode of operation of a laser-driven photodiode are used to explain the observed current-voltage characteristics. Quantum efficiencies at the two different wavelengths for eleven photocathode materials are presented.
