Abstract: The present invention relates to a method for modeling the interactions within a system between at least one object. The surface of each object defines an interface between at least two media. The set of elementary characteristic functions are chosen that correspond to the field of application in question. The physical properties of each medium considered composing the system are defined. Each object of the system is created by modeling it as a mesh and at least one elementary point source is associated with either side of each mesh element. The type of boundary conditions are determined for each interface. The global matrix for the interactions between the various objects is constructed, depending on the type of boundary conditions, the properties of the media and on the configuration of the system. The global matrix is inverted. The inverted matrix is multiplied by a column matrix containing the values of the excitation boundary conditions.

Abstract: The invention relates to a method and device for machining a target using a femtosecond laser beam. The invention consists in taking advantage of the deterministic nature of the ablation threshold and the nonlinear dependence thereof through the use of amplitude or phase pupillary filtering using the polarising effect or any other technique in order to reduce significantly the machining dimensions obtained by focusing a laser beam in nanotechnologies. One such filtering process modifies the distribution of the intensity in the focal plane such as to reduce the maximum of the central component of the spectrum of laser pulses while maintaining the bright rings below the deterministic ablation threshold. The invention associates the femtosecond ablation technique with deterministic threshold and the apodisation technique.
