Abstract
The invention relates to a medical side output high-power energy optical fiber. An SMA-905 standard joint is used as a joint of the optical fiber, and the end face of the optical fiber of the joint is plated with an anti-reflection film, wherein the film is plated according to the wavelength of transmission light, and an extramural cladding layer of the optical fiber is a biological coating. Light transmits in a fiber core and then output at the tail end of the fiber core, and the tail end is provided with a bare fiber core with a length of 2mm; the end face of the fiber core is ground into an inclined surface with 45 degrees, and a reflection film is plated on the inclined surface; the light transmitted to the tail end is reflected by the reflection film and output vertical to the side face of the optical fiber; the bare fiber at the tail end of the optical fiber and the inclined surface with the plated film are packaged by capillary tubes so as to protect the medical optical fiber from being damaged; and light energy is output from the side face.
Description
Technical field
The present invention relates to a kind of side output high-power energy optical fiber, be particularly suitable for medically, belong to the application of medical optical fiber transmission of power.
Background technology
Continuous development along with new and high technologies such as laser, it is used also more and more widely, the transmission of high-energy such as laser becomes it to the every field key in application, and medical optical fiber is the optimal selection of this high energy transmission, this is because medical optical fiber has the core skin structure, and it is by the fibre core and peripheral coaxial composition of covering at center.The ultimate principle that light is propagated in medical optical fiber is that light at the interface of different refractivity medium total reflection takes place, because the refractive index ratio covering of fibre core is high slightly, the loss ratio covering is lower, so luminous energy is mainly transmitted in fibre core.Covering is that the transmission cremasteric reflex face and the light of light is isolated, and plays certain mechanical protection effect.
At present both at home and abroad the maximum field of fiber optic applications is optical fiber communication, secondly is medical optical fiber, mostly directly exports from fiber end face and be used for the optical fiber of transmission of power, thereby has limited the application of laser medicine etc. to a certain extent.For this reason, the present invention proposes a kind of medical optical fiber of side output energy, and it is with the application of expansion of laser light, for the application of laser in fields such as medical treatment, detection, industrial processes provides great convenience.
Summary of the invention
The object of the present invention is to provide a kind of medical optical fiber of side output high-power energy, it can export energy from the side, for the application of high-energy aspects such as laser provides very big convenience.
The fibre-optical splice of the medical side output high-power energy optical fiber of the present invention adopts the SMA-905 modular connection; joint medical optical fiber end face is coated with anti-reflection film; according to transmission light wavelength plated film; it is characterized in that: optical fiber jacket is a biological coating; light propagates into tail end output in fibre core; tail end has the exposed fibre core of a segment length 2mm; the fibre core end face grinds inclined-plane at 45; plate reflectance coating; pass to terminal light through reflectance coating reflection and the output of vertical fiber side; naked fibre of optical fiber tail end and plated film inclined-plane are encapsulated by kapillary, and the protection medical optical fiber is not damaged, and luminous energy can be exported from the side.
Technical scheme of the present invention is: LASER Light Source focuses on through coupling, adjusting knob on the adjusting bracket links to each other with the two-dimensional adjustment sleeve, coupled lens is fixed on the lens focusing tube by the collet threaded circle, be placed directly in the two-dimensional adjustment sleeve, adjusting knob is scalable lens front-back direction up and down thus, adjusting the optimum position just in time overlaps focus with the medical optical fiber end face, light focuses on focus and is mapped on the fiber end face, because end face is coated with anti-reflection film, so luminous energy well enters in the medical optical fiber, thus the abundant coupling of realization light source and medical optical fiber.After light enters medical optical fiber, because cladding index is less than fiber core refractive index, do not leak outside so can only propagate in fibre core by total reflection principle light, the assurance energy does not lose.Light propagates into tail end output in fibre core, tail end has the exposed fibre core of a segment length 2mm, and the fibre core end face grinds inclined-plane at 45, plates reflectance coating, and plated film is determined according to the transmission light wavelength, passes to terminal light and reflects the output of vertical medical optical fiber side through reflectance coating.Naked fibre of medical optical fiber tail end and plated film inclined-plane sensitive for damages, but can not at will protect, influencing bright dipping, the present invention designs the kapillary encapsulation, can guarantee light output smoothly from the side, can protect medical optical fiber not to be damaged again.

Wherein, 1 be the biological coating surrounding layer, 2 for the coat of metal, 3 for kapillary encapsulation, 4 for fibre core, 5 be reflectance coating.
Embodiment:
The knot accompanying drawing is illustrated content of the present invention below.
Fig. 1 is a side output high-power medical optical fiber process chart, is exported by the side through 45 ° of inclined-plane reflections by the high-energy light that medical optical fiber transmits.
Fig. 2 is a side output high-power medical optical fiber tail end structural drawing, and light transmits the principle of having utilized total reflection in optical fiber.Light is after coupling device enters medical optical fiber, because the refractive index height of the refractive index ratio covering 1 of fibre core 4, the loss ratio covering is lower, so luminous energy is mainly transmitted in fibre core.Light propagates into tail end output in fibre core, tail end has a bit of naked fibre, and the last branch of naked fibre is coated with the coat of metal 2, conveniently is connected with other protective devices on the one hand, guarantees light total reflection on the one hand.Naked fine end is fibre core 4, and the fibre core end face grinds inclined-plane at 45, plates reflectance coating 5, and plated film is determined according to the transmission light wavelength, passes to terminal light and reflects the output of vertical medical optical fiber side through reflectance coating.Last naked fibre of medical optical fiber tail end and plated film inclined-plane can guarantee light output smoothly from the side by kapillary 3 encapsulation, can protect medical optical fiber not to be damaged again.
