Description

technical field [0001] The invention relates to a laser optical fiber, in particular to a high-power flexible optical cable and a manufacturing method. Background technique [0002] An optical fiber is a light transmission tool that causes light to be transmitted by the principle of total reflection in a fiber made of glass or plastic. A cable containing an optical fiber is called an optical cable. Usually the transmitting device at one end of the fiber uses light-emitting diodes or a laser beam to transmit light pulses to the fiber, and the receiving device at the other end of the fiber uses a photosensitive element to detect the pulses. But with the development of modern engineering technology, optical fiber is not only used for signal transmission. Various high-intensity lasers have also begun to use optical fibers for transmission. For example, nanosecond lasers or femtosecond lasers need to use energy-transmitting optical fibers for transmission. But this also puts fo...
