A technique is described for determining the electron collection distance by an electrostatic probe. A pulsed laser beam coaxial with the probe creates, by the photodetachment of plasma negative ions, a burst of electrons. The measurement of the amplitude of the probe electron current pulse as a function of the laser beam diameter indicates that the electron collection distance by the probe is twice the sheath thickness given by Kiel.On décrit une technique pour déterminer la zone d'attraction d'une sonde électrostatique. Un faisceau laser pulsé, coaxial avec la sonde crée, par photodétachement des ions négatifs, une bouffée d'électrons. La mesure sur la sonde de l'amplitude de cette impulsion d'électrons en fonction du diamètre du faisceau...
