Abstract: An optical system allows sharing of optical components and seed and pump light to achieve desired optical amplification in laser light while reducing the number of optical components and complexity of the overall optical system and achieving improved performance in lasers and reduced cost in fabrication and final lasers for large scale production of such lasers. Different optical gain sections can be used to allow for sharing of seed and pump light and sharing of optical components while providing multi-stage optical amplification.

Abstract: The present invention relates to a process for the selective extraction of monoglycerides present in a fraction of fatty acid alkyl esters (FAAEs), comprising at least one stage of liquid-liquid extraction by means of a polar solvent (PS) comprising a light alcohol and optionally of a nonpolar solvent (NS) comprising a solvent which is immiscible with the light alcohol. The present invention relates in particular to a fraction of fatty acid alkyl esters (FAAEs) of vegetable or animal origin, used in particular in biodiesels, capable of being obtained according to the process of the invention, so that its content of monoglycerides is less than 0.6%.

Abstract: The invention relates to a method for the selective extraction of functionalised fatty acid esters from seeds of oleaginous plants, wherein said method includes: a) at least one step of extracting fatty acid esters that comprises simultaneously feeding into a reactor containing said seeds a light anhydrous alcohol, a basic catalyst and an extraction solvent non-miscible with said light alcohol and in which said functionalised fatty ester is not soluble in order to obtain a mixture of esters and glycerol; b) and at least one step of selectively extracting hydroxylated fatty acid esters by feeding into the reactor said extraction solvent in a backflush direction relative to the light alcohol in order to obtain an alcohol phase enriched with fatty acid esters, a glycerol phase and a cake.

Abstract: The invention relates to a method for preparing fatty acid esters particularly used as bio-diesel fuel from whole oleaginous grains, characterized in that it comprises the following successive steps: preheating the whole non-husked grains; flattening the oleaginous grains; drying the flattened grains in order to obtain a water content and a volatile material content between 0.5 and 2.5%, and preferably between 1.5% and 2%; performing a transesterification by contacting the dried, flattened grains with an alcoholic medium in the presence of a catalyst; separating the liquid and solid phases resulting from the transesterification; neutralising the liquid phase from step d); and removing the alcohol and separating the glycerine from the fatty acid esters.

Abstract: The present invention relates to a method for reactively crushing jatropha seeds, said method making it possible, starting with specifically conditioned jatropha seeds in the presence of light alcohol and a basic catalyst, to carry out, in a single step, the crushing as well as the reaction for transesterifying the triglycerides present in the jatropha oil, thus causing an oil cake, glycerol, and fatty acid esters to be simultaneously produced. The method for processing the jatropha seeds, according to the invention, makes it possible to inactivate, in a simple, low-cost manner, the phorbol esters in addition to the curcine, thus enabling humans to handle the seeds without risk and moreover use the castor oil cake in animal feed. Characteristically, the seeds are conditioned by a series of operations that include a step of pressing the seeds and a step of drying same.
