Problems solved by technology
While the laser produces high-power laser light, a large amount of heat diffuses into the gain medium. If there is no good heat dissipation mechanism, the area where the heat is concentrated will produce a thermal prism effect, and even damage the laser gain medium.
For the sandwich structure exemplified before, when the high-power laser is output, the initial single crystal-single crystal or ceramic-ceramic bonding surface will accumulate a lot of heat and crack first, which limits its application in high-power laser devices.

Embodiment 1
[0022] Cut a piece of Yb:YAG ceramic with x=0.03 into a 30mm*20mm*1mm cuboid, and cut two YAG single crystals into a 30mm*20mm*10mm cuboid. Polish the upper and lower surfaces of all the cuboids according to YAG|Yb:YAG In the order of |YAG, three cuboids are stacked in the thickness direction, and the two adjacent sides are glued. Put the glossy sandwich composite structure into the vacuum sintering furnace, and vacuum to 9*10 -3 Pa, incubated at 1800°C for 20h to obtain the final sample.

A sandwich rare earth ion doped yttrium aluminum garnet laser material with a sandwich ceramic and single-crystal composite structure is prepared from YAG and RE: YAG and is of the structure that the YAG is located on two sides and the RE: YAG is located in the middle, wherein the molecular formula of the YAG is Y3Al5O12, the molecular formula of the RE: YAG is REx: Y3-xAl5O12, the x is greater than or equal to 0.003 but is smaller than or equal to 0.3, and the RE is Yb3+, Nd3+ or Ho3+. By the adoption of a single-crystal ceramic composite process, the ceramic of the portion combined with a single crystal is integrated with an initial single crystal to obtain the YAG ceramic coated RE: YAG single crystal or YAG single crystal caoted RE: YAG ceramic sandwich composite structure, the thermal performance of a gain medium is improved, the laser pumping intensity is improved, greater energy laser output is achieved, and meanwhile good gain output and light beam quality are obtained.
Description
technical field [0001] The invention belongs to a composite structure laser material, in particular to a sandwich ceramic single crystal composite structure laser material doped with rare earth ions of yttrium aluminum garnet and a preparation method thereof. Background technique [0002] RE:YAG is a very important laser material, wherein RE, that is, rare earth ions, refers to Yb (ytterbium), Nd (neodymium) and Ho (holmium) ions. YAG (yttrium aluminum garnet) exhibits good optical properties due to the characteristics of its cubic crystal system, and is widely used in laser gain media due to its excellent mechanical properties. YAG materials based on rare earth ion doping have various structural forms: rod-like, flake-like, columnar, optical fiber, etc., all of which have been reported. [0003] The sandwich structure designed in the present invention uses the different refractive indices of RE:YAG and YAG to realize the total reflection of the optical path, which not only...
