Multicomponent glass up-conversion white light optical fiber lighting device

Abstract

The invention discloses a multicomponent glass up-conversion white light optical fiber lighting device. The device comprises a 980 nm pumping laser, a 980 nm laser optic transmission fiber, a fiber spectroscopy and coupled system and a spirally-wound side face light-emitting multicomponent glass optical fiber. After 980 nm pumping light is transmitted through the optic transmission fiber in a long-distance mode, the 980 nm pumping light enters the two ends of the spirally-wound side face light-emitting multicomponent glass optical fiber through the fiber spectroscopy and coupled system. The core of the optical fiber is made of tellurate multicomponent glass, and the cladding is made of multicomponent glass in which tellurate is used as the base material and one or more rare earth ions are evenly doped to serve as the light-emitting center. The 980 nm pumping light can be evenly leaked towards the cladding when being transmitted by the tellurate glass fiber core with the anti-guiding refractive index, so that the rare earth ions in the multicomponent glass of the cladding are motivated, and upper energy level conversion light emitting can be achieved. White light can be given out by adjusting the intensity of the pumping light, the components of the rare earth ions and the doping content of the pumping light, the white light can be evenly output, and a comfortable and soft lighting effect is achieved.

Description

technical field [0001] The invention relates to an optical fiber lighting device, in particular to a multi-component tellurate glass up-conversion light-emitting optical fiber capable of long-distance transmission of pump light to excite doped rare earth ions, and belongs to the technical field of optical fiber lighting. Background technique [0002] The side-emitting optical fiber can be used in the lighting of flammable, explosive and other places that require photoelectric separation, and this kind of lighting is not subject to electromagnetic interference. It can also be used in special places with electromagnetic shielding requirements such as nuclear magnetic resonance and radar control rooms. It can also perform highly personalized lighting, such as decoration, outline, etc., so the optical fiber lighting device has certain practical value. [0003] The side-emitting optical fiber is the optical fiber itself as a luminous body, which can form a flexible light strip. ...

Problems solved by technology

However, due to environmental vibrations and other reasons, the core / cladding layer is easily separated at the junction, and the light scattering in the separated area is reduced, which will cause the appearance of so-called "dark defects", resulting in uneven light emission of the fiber
