Abstract: The present invention discloses an intelligent phase control method for laser coherent combination for solving the difficulties of high hardware requirements of traditional methods, low robustness of phase control methods based on deep learning. The method of the present invention is to repeatedly input the diffraction patterns after coherent combination of beams with random phases into a reinforcement learning system to update the parameters of the network inside according to the actions it performs and the rewards it obtains. After updating, the diffraction pattern is input to the network, the network outputs some values and the action corresponding to the largest value is selected and converted into a correction signal to the phase controllers, which adjusts the phase of the beam by voltage to obtain a high output. The method of the present invention can efficiently realize the phase control of the laser with high robustness and real-time performance.

Abstract: An alcohol-soluble resin and a method for preparing the same, in which the content of vinyl acetate monomer in polymeric raw material is 50% to 90%. In addition, acrylic ester monomer and other reactive functional group-containing compounds have been mixed in the raw material to ensure the performance of resin for special requirements in application. Also provided are products produced by using the resin, such as alcohol-soluble ink, composite adhesive, lustering oil for printing, glazing lacquer for woodware, superficial decorating coatings for plastic materials, safeguard coatings of metal surface and hair colorant, as well as preparation methods.

Abstract: A polyurethane-modified acrylic resin and a preparing method thereof are disclosed. The polyurethane-modified acrylic resin is prepared through the following steps: preparing a monomer with double bond and urethane group by means of a reaction of isocyanate, hydroxylalkyl acrylate and aliphatic alcohol, and then copolymerizing the monomer with acrylate monomer. The polyurethane-modified acrylic resin of the present invention contains a urethane structure, has the features of both polyurethane and acrylic resin, and is soluble in alcohol or ester solvent. An ink, a laminating adhesive, a metal surface-protective coating and a gloss varnish for woodware produced from the resin as well as the preparing methods thereof are also disclosed.
