Embodiment Construction

[0013] like figure 1 As shown, a double-ended composite growth type laser medium described in the embodiment of the present invention is a crystal whole in which two single-ended similar crystal mediums are grown together, and the crystal medium is GdVO4+Nd:GdVO4, wherein The molar concentration of Nd is between 0.1% and 3%. The doped and non-doped media of the same type are grown twice or more times to finally grow a two-terminal composite crystal media with flat interface and clear boundaries; Interface growth, after completing the entire GdVO4 growth process, through a 46-hour segmental constant temperature and cooling process, first complete the growth of a single crystal of the non-scattering flat interface of GdVO4, and fully anneal to eliminate the internal stress of the crystal, and then use the GdVO4 single crystal as a seed crystal To grow Nd: GdVO4 single crystal, this process has completed the growth process of the white-headed crystal (that is, the compound growt...

Abstract

The invention relates to a double-end equal compound growth form laser medium which is a crystal body of two single-end or three three-end similar crystal medium which grow in a compounding way; the crystal medium is selected from the following: 1) GdVO4+Nd:GdVO4; 2) GdVO4+Nd:GdVO4+GdVO4; wherein, the concentration of the Nd is between 0.1 percent to 3 percent (molar fraction). The invention has the beneficial effects: the single-end or double-end similar crystal medium is compounded by growth without thermal bonding or optical cement, thus completely realizing permanent growth among molecules; the optical character and transmission rate of a transition surface of the compound crystal is in line with the theory, therefore, the grown compound crystal can be processed by any optical and mechanical processing.

Description

technical field [0001] The invention relates to the field of optics, in particular to a dual-end compound growth type laser medium. Background technique [0002] The laser medium refers to the material capable of producing stimulated radiation, which is the core component of the laser. A conventional laser medium is a monolithic body of the same single crystal or glass without any mechanical, optical, or chemical processing or processing inside this single crystal or glass. With the development of high-power lasers, this laser medium is limited by heat dissipation, stress, size, etc., which limit the laser power and beam quality. Contents of the invention [0003] The object of the present invention is to provide a double-ended compound growth type laser medium to overcome the limitation of heat dissipation, stress and size of the existing working material, which limits the laser power and beam quality. [0004] The purpose of the present invention is to realize through ...
