Embodiment Construction

[0013] see first figure 1 , figure 1 It is a structural schematic diagram of an embodiment of the holey fiber Raman sealed cell of the present invention. The upper part of the metal sealed pool 1 uses the flange 3 to press the optical window 4; the lower center of the sealed pool 1 has a small hole 6 slightly larger than the outer diameter of the porous optical fiber, and the same position of the pressure plate 2 has a small hole 8 of the same size. A small hole 7 is pierced with a thin needle in the center of the vacuum rubber (5); one end 9 of the porous optical fiber is inserted into the Raman cell gas chamber 10 through the small holes 6, 7, and 8, and the vacuum rubber 5 is pressed by the pressure plate 2 in a flange manner. , so that the vacuum rubber 5 forms a seal with the porous optical fiber; an air hole 11 is opened on the side of the sealed pool for vacuuming and inflating or connecting a barometer 12. The other end of the holey fiber 9 is inserted into another s...

Abstract

A kind of Raman sealed cell for the stimulated Raman scattering of holey optical fiber, comprises a holey optical fiber and the metal with air-filled chamber, one end of this sealed cell is an optical window, and the center outside the other end is provided with a hole slightly larger than the diameter of the fiber. Large through holes, and a pressure plate with a through hole slightly larger than the diameter of the optical fiber in the center, and a vacuum rubber with a small hole slightly smaller than the diameter of the optical fiber in the center, and one end of the porous optical fiber passes through the pressure plate in turn The through hole of the through hole, the small hole of the vacuum rubber and the through hole on the other end face of the sealed pool are deep into the air chamber of the sealed pool, and the pressure plate forms a tight connection with the other end face of the sealed pool. Two identical sealed cells and a holey fiber form a complete set of holey fiber gas-filled Raman cells, which can be applied to holey fiber laser stimulated Raman scattering. The Raman sealing cell of the present invention is simple and practical, and is convenient for the connection and installation of the optical fiber and the Raman sealing cell.

Description

technical field [0001] The invention relates to a holey fiber laser stimulated Raman scattering, in particular to a holey fiber Raman sealing pool applied to a holey fiber laser stimulated Raman scattering. Background technique [0002] Stimulated Raman scattering has a wide range of applications, and ultra-low thresholds can be obtained by using porous fibers for laser stimulated Raman scattering. For such an application, a hermetic connection between the holey fiber and the gas-filled Raman cell must be solved. Contents of the invention [0003] The object of the present invention is to solve the problem of the sealed connection between the holey optical fiber and the gas-filled Raman cell, and provide a Raman sealed cell applied to the stimulated Raman scattering of the holey fiber laser. [0004] The present invention is realized through the following measures: [0005] A metal sealed cell, one end of the sealed cell is sealed with an optical cavity mirror, and the o...
