Novel high-power semiconductor laser energy transmission fiber

Abstract

The invention provides a novel high-power semiconductor laser energy transmission fiber which comprises a fiber body. One end of the fiber body is provided with a ceramic inserting core, and the outer surface of the ceramic inserting core is wrapped by a red copper inserting core which is connected with a heat dissipation sleeve through an adapting piece. The adapting piece and the red copper inserting core are locked tightly through a hexagon nut. A mould type stripper is fixedly arranged on the inner side of the heat dissipation sleeve through screws, and the other end of the heat dissipation sleeve is connected with a fiber protective sleeve through an adapter sleeve. According to the technical scheme, the damage to the fiber is reduced and eliminated effectively, and the transmitting capacity of the fiber to high-power lasers is improved.

Problems solved by technology

[0003] However, when using optical fibers to transmit high-power lasers, factors such as misalignment of optical fiber connectors, end face reflections, and optical damage will cause the laser to be coupled into the optical fiber. It is likely to burn the optical fiber. The problem of damage to the incident and outgoing end faces is the main factor limiting the transmission of high-power lasers by energy-transmitting fibers, so how to reduce and eliminate fiber damage and improve the transmission of high-power lasers by fibers is a problem that we need to solve
