Abstract

The invention discloses an optical cement crystal and a manufacturing method thereof and a laser chip, belongs to the technical field of laser components, and can solve the problem of poor reliabilityof a laser chip caused by poor connection strength of an optical cement crystal. The manufacturing method comprises the following steps: a laser crystal and a periodically poled crystal are bonded and connected through dangling bonds; conductive film layers are respectively arranged on the opposite end faces of the laser crystal and the periodically poled crystal which are connected; and a pulsevoltage is applied to the conductive film layers. The method is used to manufacture the laser chip.

Description

technical field [0001] The invention relates to a photoresist crystal, a manufacturing method thereof, and a laser chip, and belongs to the technical field of laser components. Background technique [0002] Cemented crystals or bonded crystals formed by connecting laser crystals and periodically polarized crystals have broad application prospects in the manufacture of all-solid-state lasers, and are also an important choice for achieving small-volume, high-stability solid-state laser output. Laser crystals and periodically polarized crystals can be connected in a variety of ways, including gluing, bonding, photoresist, etc., so as to form glued crystals, bonded crystals or photoresist crystals. [0003] Glued crystal refers to the use of epoxy resin to glue the crystals to be connected. This crystal connection method is simple to operate and suitable for large-scale production applications. However, epoxy resin is an organic compound that is volatile and causes pollution. At...
