Abstract
A Raman sealed pool for stimulated Raman scattering of porous optical fiber comprises a porous optical fiber and metal with a plenum chamber, wherein one end of the sealed pool is an optical window, the center of the outer surface of the other end of the sealed pool is provided with a through hole slightly larger than the diameter of the optical fiber, a pressing plate is provided with a through hole slightly larger than the diameter of the optical fiber in the center, a vacuum rubber is rolled with a small hole slightly smaller than the diameter of the optical fiber in the center, one end of the porous optical fiber sequentially penetrates through the through hole of the pressing plate, the small hole of the vacuum rubber and the through hole in the other end face of the sealed pool and extends into the plenum chamber of the sealed pool, and the pressing plate and the other end face of the sealed. Two identical sealing tanks and a porous optical fiber form a complete porous optical fiber gas-filled Raman tank, and the porous optical fiber gas-filled Raman tank can be applied to porous optical fiber laser stimulated Raman scattering. The Raman sealed pool is simple and practical, and the optical fiber and the Raman sealed pool are conveniently connected and installed.
Description
Technical field
The present invention relates to porous optical fiber laser stimulated Raman scattering, particularly a kind of porous optical fiber Raman sealing pond that is applied to porous optical fiber laser stimulated Raman scattering.
Background technology
Stimulated Raman scattering is widely used, and adopts porous optical fiber to carry out the laser stimulated Raman scattering and can obtain ultralow threshold value.Carry out such application, must solve the problem that is tightly connected between porous optical fiber and the inflation Raman pond.
Summary of the invention
The objective of the invention is to solve the problem that is tightly connected between porous optical fiber and the inflation Raman pond, a kind of Raman sealing pond that is applied to porous optical fiber laser stimulated Raman scattering is provided.
The present invention realizes by following measure:
A metallic seal pond, an end in sealing pond adopts the sealing of optics cavity mirror, and the other end is made a call to an aperture more bigger than the external diameter of porous optical fiber according to the external diameter of porous optical fiber in the middle in sealing pond, and porous optical fiber is taked rubber perforation way with the sealing in sealing pond.So-called rubber perforation is to prick the hole with the metal fine needle earlier in vacuum rubber central authorities, makes optical fiber can pass rubber and utilizes the elasticity of rubber self to keep and the enough friction force of optical fiber, guarantees the sealing sealing of pond under vacuum and elevated pressures condition.
Concrete technical scheme of the present invention is as follows:
A kind of porous optical fiber Raman sealing pond, it comprises that a porous optical fiber and has the metal of plenum chamber, one end in sealing pond is an optical window, the central authorities of other end outside are provided with a through hole more bigger than this fibre diameter, also have central authorities to be provided with the pressing plate of the through hole more bigger than this fibre diameter, the vacuum rubber that the aperture more smaller than this fibre diameter arranged rolls in one central authorities, one end of described porous optical fiber passes the through hole of pressing plate successively, the through hole of the aperture of vacuum rubber and sealing other end, pond also deeply seals in the plenum chamber in pond, and the other end in described pressing plate and sealing pond forms to press and is connected.
Be provided with the pit of placing for described vacuum rubber around the outer face center through hole in described sealing pond, the degree of depth of this pit is less than the thickness of this vacuum rubber, be provided with a plurality of screws that do not connect around the end face symmetrically, also be provided with a plurality of through holes accordingly around the described pressing plate, be screwed into through hole and screw with bolt the outer face in described pressing plate and sealing pond (1) is fixed.
The other end of described optical fiber also gos deep in another plenum chamber that seals the pond and encapsulates in the same way promptly constituting porous optical fiber inflation Raman pond.
The outer face in described sealing pond and the mode that is fixed of pressing plate are multiple in addition, for example spot welding connected mode.
Raman sealing of the present invention pond is simply suitable, and the connection in optical fiber and Raman sealing pond is very convenient.
Description of drawings
Fig. 1 is the structural representation of the porous optical fiber Raman sealing embodiment in pond of the present invention.
Embodiment
See also Fig. 1 earlier, Fig. 1 is the structural representation of the porous optical fiber Raman sealing embodiment in pond of the present invention.Optical window 4 is pushed down with flange 3 in the top in metallic seal pond 1; The bottom center in sealing pond 1 has an aperture 6 more bigger than porous optical fiber external diameter, and the same position of pressing plate 2 has onesize aperture 8, and an aperture 7 is pricked with fine needle by the central authorities of vacuum rubber (5); One end 9 of porous optical fiber inserts Raman pond plenum chamber 10 by aperture 6,7,8, adopts the flange mode to utilize pressing plate 2 that vacuum rubber 5 is pushed down, and makes vacuum rubber 5 and porous optical fiber form sealing; An air-filled pore 11 is opened in side in the sealing pond, is used to vacuumize and inflates or be connected rain glass 12.The other end of porous optical fiber 9 inserts another same sealing pond 1 and has just constituted the complete porous optical fiber inflation Raman pond of a cover.
