Description
Technical field
This utility model belongs to optical fiber transmission technique field, the non-welded-connecting type sapphire of more particularly to a kind of sapphire nut
Fiber-optic output cap.
Background technology
At present, when transmitting high power laser light with energy-transmission optic fibre, energy-transmission optic fibre incidence end and exit end facet damage problem are
Limit fibre transmits the principal element of high power laser light；When laser power very little, fiber end face is not any change, when laser work(
After rate gradually increases, because fiber end face is not absolute cleaning, spot can make end face substantially hole shape impaired loci occur, but not affect light
Fine transmission laser, but with the further increase of laser power, partial melting phenomenon is will appear from, while end face surface generation is micro-
Little deformation, and plasma is produced after laser power reaches damage threshold, to glisten with plasma and sound, optical fiber output swashs
Under light energy, if continuing irradiating laser pulse, it will serious melting phenomenon occur, optical fiber surface also seriously will be broken
It is bad.
The scheme for solving fiber end face damage is to increase end cap configuration before fiber end face, and end cap can be prevented effectively from peak
Under value power, laser is damaged to fiber end face.
