Problems solved by technology

At present, there is no patent for evaluating the matching degree of refractive index of neodymium glass wrapping. According to Fresnel's law, the present invention proposes to characterize the neodymium glass wrapping by measuring the reflection of the interface between the neodymium glass and the glued layer and the comprehensive result of the interface reflection between the wrapping glass and the glued layer. Refractive index matching, the sum of the interface reflection between neodymium glass and glued layer and the interface reflection between edged glass and glued layer is called the residual reflection of neodymium glass edged

Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention should not be limited thereby.

[0033] Such as figure 1 As shown, the neodymium glass edging residual reflectance detection device of the present invention includes a first laser 1, other wavelength lasers 2, a total reflection mirror 3, a beam shaping lens group 4, a beam splitter 5, a sample 6, a laser intensity detector 7, Data processing system 8 and residual reflection detector 9 . Wherein the other wavelength lasers 2 and the total reflection mirror 3 are indicated by dotted lines, showing that these two parts are not needed at ordinary times, and can be added when needed. Sample 6 as figure 2 As shown, it includes neodymium glass A, glued layer B and edged glass C, and the neodymium glass and edged glass are connected to each other through the glued layer. The sample 6 is placed on a ...

Description

technical field [0001] The invention relates to the detection technology of neodymium glass, in particular to a detection device and detection method for residual reflection of the wrapping of neodymium glass. Background technique [0002] Neodymium glass is widely used as a laser material. It has a large absorption spectrum range, a large absorption coefficient, a high fluorescence lifetime, and a large stimulated emission cross section. It is a four-level system with good spectral properties and is very suitable as a laser material. Neodymium glass has a good and mature melting process, and can manufacture products of various specifications and sizes, especially super-large-size neodymium glass is currently the most mature and reliable amplification medium for high-power laser systems, and is widely used in various high-power laser devices in the world. For example, the National Ignition Device in the United States, and the Shenguang Project in my country. When neodymium g...
