  • Process and apparatus for producing electrons using a field coupling and the photoelectric effect
    Patent number: 4845365
    Abstract: According to the invention, under glancing incidence a first radiation (6) in the infrared range and which is linearly polarized is supplied to a target (2) made from a non-electrically insulating material and simultaneously to said target is supplied under a non-glancing incidence a second radiation (8) in the visible or ultraviolet range, in such a way that a same zone of the target is reached by the first and second radiations, the polarizing plane of the first radiation also being such that it contains a perpendicular to said zone, which then produces electrons.Application to the production of free electron lasers.
