Abstract
The hollow GeO2 optical fibre suitable for CO2 laser is made up through forming a layer of GeO2 film on inner wall of quartz tube by optical deposition, and drawing optical fibre. By heat treatment at 1000 deg.C, GeO2 crystal becomes hexagonal system. It features high capacity and transmission power and easy use.
Description
The present invention relates to a kind of germanium dioxide hollow optical fibre, belong to the photoelectron material field, be specially adapted to transmit CO
2Laser energy.
Present existing crystal optical fibre is at transmission CO
2During laser energy,, determined that its ability to bear is low, so can not transmit the above high power laser light of 50W for a long time because of its intrinsic characteristics.Influenced CO like this
2The transmission of 10.6 μ m infrared lasers of laser instrument has limited the usable range of the application laser of aspects such as medical treatment, machining.
The objective of the invention is to develop a kind of germanium dioxide hollow optical fibre, less than 1, transmission of power can reach more than tens watts its refraction coefficient at 10.6 μ m places, like this can be CO
2The high-energy of laser passes to the position of required use, as thin, long, the soft optical fiber of used for medical procedures can be insinuated into human body than the position, deep.
Technical scheme of the present invention is to be base material with quartzy hollow optic fibre, utilize chemical vapor deposition or spraying technology, at the fixing one deck germanium dioxide film of quartz ampoule inwall, be made into hollow optic fibre with the silica fibre wire drawing machine, again through 1000 ℃ thermal treatment, change the germanium dioxide in the optical fiber into hexagonal, its refraction coefficient at 10.6 μ m places less than 1.In this optical fiber, can transmit the laser energy of different capacity.But this optical fiber free bend.According to using needs to add the reinforced plastic protection at fiber outer layer.
Advantage of the present invention is that the method for manufacturing germanium dioxide hollow optical fibre is simple.Quartz and germanium dioxide fusing point height, ability to bear is strong, can transmit high power laser, because at 10.6 μ m places, Nr is less than 1, so power attenuation is little, generally only is 1.0dB/m to 3dB/m.Therefore, this optical fiber is easy to practicability, and is easy to use.
Enumerate two embodiment below:
Example 1: the high grade quartz pipe with 60mm length, internal diameter 13mm, external diameter 14mm is made base material, on the CVD lathe with GeCL
4Be raw material, with GeO
2Deposit on the quartz ampoule inwall.In deposition process, in addition suitably cooling makes GeO
2Deposit more fully.So just making with the quartz glass is base material, with GeO
2Being skin, is the GeO of core with the air
2Hollow prefabricated rods.This prefabricated rods is carried out wire drawing on wire drawing machine, make hollow optic fibre, put into annealing furnace then and anneal, make GeO with 1000 ℃
2All be transformed into hexagonal.Fiber outer layer is coated polyacrylic resin, is protected with heat-shrink tube then.The germanium dioxide hollow optical fibre of making like this can be imported the above CO of 50W
2Laser power, loss is 1.0-3.0dB/m only.Bending radius is 14mm.
Example 2: the high grade quartz pipe with 60mm length, internal diameter 13mm, external diameter 14mm is made base material, with the GeO of hexagonal
2Pack into equably in the pipe,, slowly tilt to rotate glass tube, make GO with the oxyhydrogen combustion knot
2Equably attached on the inner tubal wall.The method of use-case 1 is carried out wire drawing and annealing, and germanium dioxide hollow optical fibre is made in coating and reinforcing.This optical fiber can be imported the above CO of 50W
2Laser power, loss are 3.0dB/m.Bending radius is 14mm.
