Abstract: Disclosed is a servo matching control mid-infrared differential dual-wavelength laser based on Nd:MgO:PPLN, The 813 nm semiconductor pumping source, the energy transmitting optical fiber, the first focusing lens, the second focusing lens, the first 45-degree beam splitter, the mid-infrared idle frequency light output mirror, the polarized crystal, the servo motor, the mid-infrared parametric light total reflection mirror, the microprogrammed control unit, the second 45-degree beam splitter, the electro-optical crystal and the 1093 nm fundamental frequency light total reflection mirror are sequentially placed from right to left in a straight cavity of the laser; and the 1084 nm fundamental frequency light total reflection mirror is placed in a bent-shape cavity of the laser, corresponding to a position of the second 45-degree beam splitter, such the second 45-degree beam splitter can reflect incident light to the 1084 nm fundamental frequency light total reflection mirror.

Abstract: An output-decision-based negative feedback control method and system. The method includes: receiving, by an output decider, output responses of at least two heterogeneous functional equivalents, and dividing numbers corresponding to the at least two heterogeneous functional equivalents into at least one set according to the output responses; determining, by the output decider, credibility of each set according to the output responses, and sending the at least one set and the credibility corresponding to each set to a feedback controller via decision information; generating, by the feedback controller, a first scheduling policy and/or a second scheduling policy according to the decision information; and sending, by the feedback controller, the first scheduling policy to an input proxy, and/or sending a change instruction to the heterogeneous functional equivalent indicated by the second scheduling policy. The method can prevent in advance and process a heterogeneous functional equivalent that may be faulty.
