METHOD AND DEVICE FOR CREATING A SOURCE OF RADIATION PULSED IN THE RANGE OF TERAHERTZ AND APPLICATION BY REALIZING SAID METHOD

摘要

The invention relates to a method for creating a terahertz source (4). For said purpose, a filament (5) is generated from a femtosecond laser beam (2). The filament (5) is a plasma column situated on the propagation axis of the laser beam. The source (4) of terahertz radiation consists of all the punctual sections of the filament (5). Said source emits a terahertz radiation (6) according to an emission cone directed according to the propagation axis of the impulses of the laser (2). The terahertz source (4) can be placed in proximity of a target to be irradiated. Dislocation is performed by dislocating the laser beam (2) at the origin of the filament (5).
