Abstract: In a nonlinear optical medium such as the gallium arsenide, two collinear incident monochromatic waves are injected to generate a monochromatic wave. The medium induces between the three waves a propagation phase-shift that has a value π if the three waves travel a coherence length in the medium and that is compensated at the value 0 modulo 2π each time that the three waves have travelled a periodic distance in the medium. In order to significantly increase the conversion efficiency, the periodic distance between two successive bounces of total internal reflection of the waves in zig-zag is strictly less than the coherence length. The high conversion efficiency on a very short material length leads to product high-power coherent optical sources particularly with wavelengths of approximately 10 μm.

Abstract: The application relates to a method for analyzing the wave surface of a light beam from a source to the focus of a lens. The beam illuminates a sample on the analysis plane and having a defect. A diffraction grating of the plane is a conjugate of an analysis plane through a focal system. An image is formed in a plane at a distance from the grating plane and analyzed by processing means. The invention encodes this grating by a phase function resulting from the multiplication of two phase functions, a first exclusion function defining a meshing of useful zones transmitting the beam to be analyzed in the form of light pencil beams, and a second phase fundamental function which creates a phase opposition between two light pencil beams coming out of adjacent meshes of the exclusion grating.

Abstract: A device for analyzing the wave surface of a light beam has an entry lens which defines a reference plane, optically conjugate with the plane in which the wave surface of the light beam is analysed. A bidimensional meshed lattice is placed in this reference plane, perpendicularly to the beam. The different sub-beams, due to the different orders of diffraction, are focused jointly by a first lens, in an intermediate focal plane, in the vicinity of which a mask selects, from the sub-beams, those which relate to at least three distinct orders of diffraction. A second lens takes the selected sub-beams to a nil-sensitivity plane, conjugate with the plane of the lattice. An interference image is observed in a working plane, situated at a chosen distance from the nil-sensitivity plane. The device can be characterized as an improved achromatic optical interferometer, of the trilateral shift type.
