Description
Technical field
The present invention relates to a kind of all -fiber air chamber system and its implementation, particularly base with gas circulation function
In hollow-core fiber with drawing the real core fibre of cone processing to dock encapsulation in high precision, and by cutting serial openning on hollow-core fiber surface
Realize all -fiber air chamber system and its implementation of gas circulation function.
Background technology
Free boundary type hollow-core fiber is a kind of New type hollow optical fiber developed rapidly in recent years, is employed and tradition
The different guide-lighting principle of silica fibre total internal reflection, the main air fibre that light wave is strapped in micron dimension using antiresonance principle
It is transmitted in core, has the characteristics that simple in construction, design is convenient, transmission loss is low, nonlinear effect is weak.By in hollow light
Fine internal filling gas, both can effectively increase the interaction area and action intensity of light wave and gas, can utilize again low
Loss transmission characteristic ensures the interaction distance.At present, this hollow-core fiber is adjusted in optical fibre gas laser device, from phase
It is used widely in the research of the two-phonon process such as system, stimulated Raman scattering, four-wave mixing, is especially considered and realizes high power
A kind of technological approaches for having much potentiality of mid-infrared fiber laser.Optical fibre gas laser utensil has gas laser high power defeated
The potentiality gone out, but not only need to consider to dock encapsulation with the low-loss of the real core fibre of tradition in the case of high power, it is also necessary to
Consider the circulatory problems of gas, it is the key of realizing high-power output to take away used heat using gas circulation.Hollow-core fiber at present compared with
The gas mainly coupled for common hollow-core fiber air chamber preparation scheme including light wave by external optical window with hollow-core fiber
Body structure, real core fibre and hollow-core fiber are directly put into vacuum constant-pressure cavity two ways.By will be filled with specific gas
Hollow-core fiber both ends and single-mode fiber welding, so as to form brand-new full fiber type air chamber have simple in construction, small volume,
Outstanding advantages of easy to use.But existing technical scheme is mainly by using the directly fused mode of arc discharge.It is directly right
Connect the fusion techniques that welding general single mode fiber is employed using arc discharge scheme, mainly by rationally control discharge time,
Strength of discharge and discharge time realize the directly fused of hollow-core fiber and real core fibre.This scheme does not account for hollow-core fiber
The outstanding features such as aperture is micron order, characteristic dimension is small, are relatively suitably applied real core photonic crystal fiber welding, for hollow light
For fibre, arc discharge can inevitably result in airport avalanche, be recessed so as to cause hollow-core fiber cross section destroyed,
