The angle of long and slender core material total internal reflection, laser energy are penetrated in the form of total internal reflection to optical fiber side front direction in optical fiber end end face
Out, the conical outside through optical fiber is towards output in front of optical fiber side.In above-mentioned optical fiber connector end face and shaft axis of optic fibre in 38 degree
In the case of, before laser side between output angle and shaft axis of optic fibre be 76 degree of angles.The shortcomings that this method, is that fiber end face needs
The circle side output of cylindrical fiber, the cylindrical side are actually passed for the laser of the optical flat of better quality, and output
The curvature in face is determined by the thickness of optical fiber, if having special requirement to the angle of divergence of laser energy output in actual use, optical fiber
The side curvature of oneself often makes problem increasingly complex in itself.
The purpose of the present invention is to provide a kind of side and penetrates medical laser optical fiber, the direction of laser side-shooting and the angle of shaft axis of optic fibre
Degree can be close in 90 degree or other controllable angles.Laser is by optical fiber when laterally being exported simultaneously, and the curvature of optical fiber side can be with
Curvature for the cylindrical surface determined different from optical fiber thickness itself.
Summary of the invention
The design and processing of medical laser optical fiber are penetrated in a kind of side, and the direction of laser side-shooting and the angle of shaft axis of optic fibre can connect
It is bordering on 90 degree or other controllable angles.Laser is by optical fiber when laterally being exported simultaneously, the curvature of optical fiber side can for different from
The curvature on the cylindrical surface that optical fiber thickness itself determines.
