Abstract
The present invention belongs to the field of optoelectronic material. The key point of the present invention is that the glass capillary carrier is first coated with one layer of 0.1-0.2 mm thick silicone rubber in the outer surface and then plated with silver in the inner surface via chemical liquid phase deposition process, and partial silver is iodized to form inner silver iodide film, with the thickness of the silver iodide film being selected based on the wavelength of transmitted laser radiation. The present invention is suitable for transmitting CO2 laser, CO laser, Er: YAG laser radiation with transmission loss less than 0.5 dB/m and fiber inner diameter being 0.3-1.8 mm. This kind of fiber is mainly used in surgical operation, machining and other fields, and has the advantages of flexible operation, great transmitted power and less transmission loss.
Description
The invention belongs to the photoelectron material field
At present, transmission laser energy optical fiber can be divided into two big classes by structure: real core fibre and hollow-core fiber.Real core fibre can produce that end face reflection, output beam are dispersed, through-put power is low, cost is high, can't carry out widespread use.Hollow-core fiber also can be divided into hollow plastic fiber, hollow metal optical fiber, hollow sapphire fiber and hollow glass optical fiber by carrier, and the rough surface of hollow plastic fiber, hollow metal optical fiber, hollow sapphire fiber, make laser beam produce scattering, therefore the loss of this type optical fiber is bigger, and hollow plastic fiber can't be used to transmit high power laser.Hollow glass optical fiber smooth surface, flexibility is good, through-put power is big.
The objective of the invention is to prepare that loss is little, through-put power is big, soft, use hollow quartz glass optical fiber flexibly, thereby enlarge the usable range of carbon dioxide laser, carbon monoxide laser and Er:YAG laser, make existing laser instrument upgrading.
This silver/silver iodide hollow glass optical fiber comprises hollow glass carrier 2, protective seam 1, and compositions such as interior metal-coated membrane silver 3 and deielectric-coating silver iodide 4, it is characterized in that: glass carrier 2 is evenly circular tubular glass, also can be even Taper Pipe shape glass; Deposition layer of metal silver 3 on the inwall of vitreum 2, its thickness is 0.5～2.0 μ m, is layer dielectric silver iodide 4 at the inside surface of metal silverskin 3, and its thickness is 0.5～6.0 μ m, and the outside surface of glass carrier 2 is silicon rubber protective seams 1.
