摘要： A method and device is provided for characterizing microscopic elements. A source signal may be chopped by means of microsystems of opto-electromechanical elements (MOEMS), which gives rise to temporal modulation of the excitation signals. The method of characterizing microscopic elements involves propagating a dispersed light source signal, spatially chopping the spectrum of the source signal into at least two excitation signals having predetermined wavelengths λi, coding the excitation signals, focusing the excitation signals in order to generate a sensor signal propagated towards a measurement zone, and analyzing an interaction signal issuing from the interaction of the sensor signal with the microscopic elements situated in the measuring space. The spatial chopping of the spectrum of the source light signal is performed by a microsystem of opto-electromechanical elements (MOEMS).

摘要： The present invention relates to a multi-pass three-dimensional amplifier structure in which a beam of light traverses an amplifier medium multiple times via distinct multiple paths. The distribution of the multiple paths being such that the volume occupied by the multiple paths inside the amplifier medium substantially overlaps with the volume of the amplifier medium being optically pumped by an optical pump beam. The distribution of the optical paths is such that no more than two of the multiple paths lie in a same plane. The astigmatism induced by anisotropic amplifying crystals is self-compensated by aligning the crystallographic axes of the amplifying crystal at a 45° angle to the longitudinal axis of the redirecting means.

摘要： The present invention relates to a process for manufacturing alkanes, comprising, as main stage, a reaction resulting from bringing methane into contact with at least one other starting alkane (A) in the presence of a catalyst based on a metal M capable of catalyzing a metathesis of alkanes. The reaction results in the formation of at least one or two final alkanes (B) having a number of carbon atoms less than or equal to that of the starting alkane (A) and at least equal to 2. Preferably the catalyst comprises a hydride of a metal M grafted to and dispersed over a solid support. The metal M may be chosen from transition metals, lanthanides and actinides. The present invention also relates to the use of a catalyst capable of catalyzing a metathesis of alkanes in 3 reaction resulting from bringing methane into contact with at least one other starting alkane (A).
