Abstract

The invention relates to a novel ultraviolet transmission optical fiber and a preparation method thereof. The section structure of the ultraviolet transmission optical fiber comprises a pure silicon quartz fiber core layer, a fluorine-doped quartz depressed inner cladding layer and a pure silicon quartz outer cladding layer, a changing gradient refractive index structure is adopted on two transition layers between the depressed inner cladding layer and the pure quartz core layer as well as between the depressed inner cladding layer and the outer cladding layer. The optical fiber can be used in windows below 600nm, has lower attenuation in ultraviolet wavelength windows, and can keep stable transmission characteristics during use. The optical fiber has extensive application in the fields of industrial application, optical fiber sensing, optical fiber medical treatment and the like.

Description

technical field The invention relates to a transmission optical fiber and a preparation method thereof in the fields of industrial application, optical fiber sensing and medical treatment, in particular to a novel ultraviolet light transmission optical fiber and a preparation method thereof. The optical fiber can be used in the window below 600nm, has low attenuation in the ultraviolet wavelength window, and can maintain its stable transmission characteristics during use. The optical fiber is widely used in industrial applications, optical fiber sensing, and optical fiber medical fields. Background technique Ultraviolet laser has the characteristics of short wavelength, high energy, no thermal effect, and direct bond breaking when interacting with substances. Using optical fiber to transmit ultraviolet laser can introduce ultraviolet laser to long-distance complex work targets, greatly expanding the application range of ultraviolet laser. For example, with the help of ultr...
