Description

Technical Field

[0001] The utility model relates to the technical field of optics, in particular to a Pockels cell mounting seat with adjustable angle. Background Art

[0002] The Pockels cell is a laser modulator based on the electro-optic effect, which can be used as a Q switch in Q-switched lasers. The Pockels cell has the characteristics of small size and low absorption rate.
