Light guiding properties of soap films.

Janine Emile

Résumé

The injection of a laser beam from the side in a horizontal free-standing draining soap film is reported. We observe the self-deflection of the beam that varies in a random way. The film thinning is affected by the injection and depends on the polarization of the light beam, not on the laser power. The liquid in the soap film is ejected towards the meniscus, without modifying its molecular structure. Besides, this injection seems to stabilize the film near the light beam propagation and to destabilize the film in the other zones. Consequences and applications are then discussed.
