Abstract

The invention discloses a detecting device and a detecting method for covered edges of large-size neodymium glass with the covered edges. The detecting device comprises a first laser source, a beam shaping lens system, a spectroscope, a first total reflector, a beam positioning system, a sample to be tested, a laser intensity detector, a residual reflection detector and a data processing system. The components of the detecting device are arranged in such a manner that the beam shaping lens system and the spectroscope are sequentially arranged along a laser output direction of the first laser source, the spectroscope divides incident light into transmitting light and reflected light, the laser intensity detector is arranged in the direction of the incident light, the first total reflector, the beam positioning system, the sample to be tested and the residual reflection detector are sequentially arranged in the direction of the transmitting light, and an output end of the laser intensity detector and an output end of the residual reflection detector are connected with an input end of the data processing system. The detecting device and the detecting method have the advantages that residual reflection of the covered edges with different incident angles and at different positions can be measured according to actual conditions, and measurement precision is high.

Description

Technical field [0001] The invention relates to a detection technology for neodymium-doped laser glass (neodymium glass for short), in particular to a detection device and a detection method for the residual reflection of a large-size neodymium glass edging edge. Background technique [0002] Neodymium glass is widely used as a laser material. It has a large absorption spectrum, a large absorption coefficient, a long fluorescence lifetime, a large stimulated emission cross section, and a four-level system with good spectral performance, making it 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 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 Proje...
