The properties of a GaAs electron source have been investigated through experimental work. Laser excitation can generate abnormal energy distributions in the photoemittedelectronbeam. We demonstrate that lasermodes are responsible for such an anomalous spread, which can be prevented by using a single mode light source.

Abstract
The properties of a GaAs electron source have been investigated through experimental work. Laser excitation can generate abnormal energy distributions in the photoemittedelectronbeam. We demonstrate that lasermodes are responsible for such an anomalous spread, which can be prevented by using a single mode light source.File in questo prodotto:
