The utility model is characterized in that a metallic film (2) is coated on the inner surface of the quartz glass capillary parent tube (1). The utility model can be used for transmitting ultraviolet laser with high power.
Description
Technical field
The utility model relates to a kind of hollow-core fiber, is specifically related to a kind of hollow-core fiber that can be used for transmitting ultraviolet laser.
Background technology
In recent years, the high power Ultra-Violet Laser has obtained at aspects such as bioengineering, medical science, materials processing, laser anti-counterfeits using widely.For this Laser Transmission is arrived narrow space, carry out laser diagnosis and treatment, Laser Micro-Machining or surperficial little processing, the development of its transferring material is crucial.As far back as the eighties, the Ultra-Violet Laser Transmission Fibers is compared systematic research abroad, thereby the Optical Fiber Transmission performance is greatly improved, 1987-1992 Germany has carried out one and has been called the plan of " laser research and laser technology ", emphasis is supported the application of laser technology, formulated the plan of " laser 2000 " in 1993 again, the Ultra-Violet Laser technology has been listed in emphasis research topic support, Minnesota Mining and Manufacturing Company has the commercial UV fiber of part.Domestic research work is in this respect carried out later, and units such as Chinese building material research institute mainly concentrate on the research of quartzy real core fibre transmitting ultraviolet laser aspect, and according to the latest news, maximum transmission power is about 80～100mJ.And the high power Ultra-Violet Laser scope that more is widely used at aspects such as optical waveguide preparation, photoetching, therefore development transmission high power Ultra-Violet Laser Transmission Fibers just seems particularly important.
Since Hidaka in 1981 proposes the thought of infrared hollow-core fiber first, the development of hollow-core fiber is subjected to the common concern of Chinese scholars, from then on progressively started the upsurge of competitively developing hollow-core fiber at the superlaser transmission field, northeastern Japan university, U.S. Lu Te add university, Israel Tel Aviv university etc. and one after another hollow-core fiber have been carried out extensive studies, proposed the hollow-core fiber and the technology of preparing thereof of different structure and type, but what studied is transmission infrared laser hollow-core fiber mostly.
In view of many-sided advantages such as hollow-core fiber surface damage for no reason, energy damage threshold height, can be used for transmitting the high-energy Ultra-Violet Laser, it should be the most attractive a kind of selection in current laser medicine and the Laser Processing transmission system.Therefore, research transmitting ultraviolet laser hollow-core fiber, and make it can carry out the stable transmission of high-energy low-loss to be to carry out the basis that Ultra-Violet Laser is used, also to be imperative trend.
Summary of the invention
But the purpose of this utility model is to provide a kind of hollow-core fiber of transmitting ultraviolet laser.
Implementation of the present utility model is: a kind of hollow-core fiber that can be used for transmitting ultraviolet laser; it comprises quartz glass capillary parent tube 1; outside the quartz glass capillary parent tube 1 protective finish 5 is arranged, it is characterized in that being coated with metallic film 2 on quartz glass capillary parent tube 1 inside surface.
But aforesaid metallic film 2 outer also coated glass films 3, the organic macromolecule membrane 4 of glass film 3 outer coatings.
The utility model utilizes the highly reflective energy of metallic film to Ultra-Violet Laser, metallic film 2 is coated on laser quartz glass capillary parent tube 1 inside surface, thereby reach effective output of Ultra-Violet Laser, coated glass film 3 has increased reflectivity on metallic film 2, has better transmitted Ultra-Violet Laser.The protection to metallic film has been strengthened in the coating of organic polymer film 4, has prolonged the serviceable life of optical fiber.
