Abstract

Disclosed are a large size laser neodymium glass cladding size and angle non-contact detection device and a large size laser neodymium glass cladding size and angle non-contact detection method. The large size laser neodymium glass cladding size and angle non-contact detection device is composed of an optical system, a mechanical system and a signal processing and controlling system, wherein the optical system is composed of high brightness coaxial light sources, area array cameras, a telecentric lens, a laser displacement sensor, a manual platform and an electric displacement platform, the mechanical system is composed of an air floatation cushion, a marble base plate, a positioning block, a photoelectric detector and a guide rail, and the signal processing and controlling system is composed of a data collection and control system, a data transmission and control line and a computer. The large size laser neodymium glass cladding size and angle non-contact detection device and the large size laser neodymium glass cladding size and angle non-contact detection method can perform non-contact automatic detection on the size and angles of laser neodymium glass during the large size laser neodymium glass cladding bonding process, can not introduce defects into cladding faces, have the advantages of being easy in measuring, high in accuracy and high in efficiency, and obtain dimensional accuracy superior to 0.02mm, angle accuracy superior to 2' and efficiency superior to 2min / slice.

Description

technical field [0001] The invention relates to the detection of laser glass, in particular to a non-contact detection device and method for the size and angle of laser neodymium glass in the process of edging and bonding of large-size laser neodymium glass. Background technique [0002] Laser neodymium glass is widely used as a gain medium for high-power laser systems. However, when the laser neodymium glass is used as the gain medium, the stimulated amplified spontaneous emission (ASE) will affect the utilization of its energy storage efficiency. Therefore, in order to suppress the stimulated amplified spontaneous emission, it is necessary to bond a layer on the side perpendicular to the light passing direction. Absorbing stimulated amplified spontaneous emission absorbing medium, called laser neodymium glass edging. Before edging, there are strict requirements on the size and angle of the side processing of the neodymium glass. For example, the square size laser neodymiu...
