Description

technical field [0001] The invention relates to a large-scale grating precision adjustment device, which is mainly used for the line width narrowing module of the laser and the stable control of the wavelength of the laser. Background technique [0002] In an optical system using a large-size grating, the most common method is to use a combination of a pitch adjustment mount and a height adjustment mount, that is, to fix the large-size grating on the pitch adjustment mount through a clamp, and then install the pitch adjustment mount on the height adjustment On the shelf, so as to realize the adjustment of large-size grating. However, due to the large size of the large-scale grating, this solution has a large structural size and poor stability, which makes it difficult to be used in the system, thus limiting its application. Contents of the invention [0003] The object of the present invention is to provide a large-scale grating precision adjustment device. The device ha...
