Abstract

The invention provides a laser crystal polishing device, which belongs to the field of polishing equipment. The laser crystal polishing device comprises a rack, a polishing disc, a first drive device,a placing disc, a holder and a second drive device. The polishing disc can be rotatably arranged on the rack; the first drive device is used for driving the polishing disc to rotate around a verticalaxis relative to the rack; a placing hole for placing a crystal is formed in the placing disc; the placing disc is placed on the polishing disc; the holder can be movably arranged on the rack, and holds the placing disc onto the polishing disc; and the second drive device is used for driving the holder to move toward a direction close to or far away from the vertical axis relative to the rack. According to the laser crystal polishing device, the second drive device can change a position of the placing disc on the polishing disc, so that not only can the crystal be roughly polished, but also the crystal can be finish-polished.

Description

technical field [0001] The invention relates to the field of polishing equipment, in particular to a laser crystal polishing device. Background technique [0002] High-efficiency laser crystals LBO, YCOB and other nonlinear optical crystals are key nonlinear materials for ultra-short and ultra-intensive lasers. This type of crystal has a wide transmission range, moderate nonlinear coefficient, high damage threshold and good Chemical and mechanical properties, widely used in laser frequency doubling and strong laser fields such as optical parametric oscillators and optical parametric amplifiers. When polishing the crystal, it is generally necessary to use different equipment to complete the rough polishing and fine polishing of the crystal, and the polishing process is extremely troublesome. Contents of the invention [0003] The object of the present invention is to provide a laser crystal polishing device to improve the troublesome problem of rough and fine polishing of ...
