Conical Interfaces between Two Immiscible Fluids Induced by an Optical Laser Beam

Résumé

We demonstrate the existence of conical interface deformations induced by a laser beam, that are similar to Taylor cones in the electrical regime. We show that the cone morphology can be manipulated by fluid and laser parameters. A theory is proposed to quantitatively describe these dependences, in good agreement with experimental data obtained for different fluid systems with low interfacial tensions. Counter-intuitively the cone angle is proved to be independent of the refractive index contrast at leading order. These results open a new optofluidic route towards optical spraying technology-analogue of electrospraying-and more generally for optical shaping of interfaces.
