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 during the encapsulation and bonding of large-size laser neodymium glass. Background technique [0002] Laser neodymium glass is widely used as a gain medium in high power laser systems. However, when laser neodymium glass is used as a gain medium, since the stimulated amplified spontaneous emission (ASE for short) will affect the utilization of its energy storage efficiency, in order to suppress the stimulated amplified spontaneous emission, it is necessary to bond a layer on the side perpendicular to the direction of light transmission. Absorbing Stimulated Spontaneous Emission Absorbing Medium, called Laser Nd Glass Encapsulation. Before edging, there are strict requirements on the size and angle of side processing of neodymium glass. For example, the square-sized laser neodymium glass cur...
