Disclosed is a three-dimensional cross waveguide type medium pool for a serial laser combination in Brillouin amplification, which relates to a medium pool. The invention solves the problem that to suffice the laser incident beam and the emission beam at two directions is difficult, and to adjust the fine cross and overlapping of the two laser beams in the medium pool is also difficult in the prior noncollinear structure medium pool of the serial laser combination. A first subassembly and a second subassembly of the invention are symmetrically arranged at the two ends of a square component (10); a first component (1), a second component (2), a third component (3) and a fourth component (4) are respectively arranged at the four side walls of one end of the square component (10); a fifth component (5), a sixth component (6), a seventh component (7) and a eighth component (8) are respectively arranged at the four side walls of the other end of the square component (10). The medium pool of the invention makes the laser beam to be perpendicular to the injection window when the laser beam is injected into the medium pool, and fulfils a larger cross angle within the limitation of the permitted errors of the wave vector mismatch angle. The medium pool of the invention also simplifies the structure, increases the energy conversion efficiency, and realizes the cross and overlapping of the laser beam in the medium pool with convenient adjusting.

The invention relates to an organic light-emitting display cathode ring anti-reflection structure, a manufacturing method thereof, and a display. The cathode ring anti-reflection structure includes a cathode ring, and a first barrier layer, a second barrier layer, and a first barrier layer sequentially fabricated on the cathode ring. Three barrier layers; the first barrier layer is in direct contact with the surface of the cathode ring, and is fabricated on the cathode ring by evaporation. In the present invention, the color filter layer is manufactured on the cathode ring at the same time in the process of manufacturing the color filter layer in the display area of ​​the organic light-emitting display, and the color filter layer is arranged on the cathode ring in a stacked manner, so that visible light cannot be transmitted. Through the film layer, the purpose of reducing or even eliminating the visible light reflection of the cathode ring is achieved, and the structure does not need to add additional processes and equipment in the production process, which can not only effectively solve the problem of cathode ring reflection, but also will not increase the production cost. The production process Simple and easy.
