Square core optical cable SCF series

SCF manufactured by YOEC belongs to large core-diameter Beam delivery fiber, whose core is square or rectangular, generally in high purity quartz. The optical cladding is a kind of doped glass material deposited by chemical vapor deposition. Background At present, the core geometry of optical fiber is almost circular structure. In the development and application of fiber laser, the output beam is Gaussian beam, and the energy is concentrated in the center part, which is easy to damage the optical device. At the same time, the Gaussian beam will bring non-uniform heating to the device, which will greatly affect the quality of the beam. It is suitable for cutting in central high-intensity areas. However, welding, photolithography and semiconductor wafer processing require a more uniform beam profile, namely a flat-top beam, which not only increases the damage threshold of the entire optical system, but also minimizes the influence of thermal effects on beam quality. The application requirements in many fields are the driving force for the development of laser technology. At this time, there is an urgent need for a technical means that can transform Gaussian beam into a specified beam, namely laser beam shaping. The arrival of laser beam shaping makes the laser beam can be converted into a variety of uniform energy distribution according to the demand, which further promotes the development of laser technology, but also improves the application level of laser technology.
