The ability to couple light from one fiber to another greatly expands upon IPG’s fiber laser functionality. A single laser can be used as a power source for multiple work cells thus reducing the total cost of capital equipment. A multi-port unit offers the option of attaching varied process fibers where each work cell could be operating on a different application; for instance one port could weld with a 300 μm diameter fiber in one cell while another port operates with a 100 μm fiber thus providing power to two workstations from a single laser. In addition to greater functionality, optical coupling also provides for ease of replacement of the process fiber, be it for altering the parameters for an application or in an instance of accidental damage to the fiber. If damage does occur, the main power source stays intact and operational for other channels, thus providing greater protection to the power source.
Available options include a single port coupler, a multi port beam switch offered in 2, 3, 4, 5 or 6 channels, or a 2 port beam sharing function with the additional option of 100% full power in one port. Each component is available in a multitude of configurations depending on the chosen power source, series and the size of the component. Up to 2 ports can be integrated internally in the YLS series with either top or side mount depending on the desired end use. External optical ports have the added option of a long stand-off distance for remote installation on the work floor for greater flexibility and convenience. Though the beam sharing function is only available as a 2 port system it can also be combined with the multi-port beam switch for even greater capabilities.
Depending on the power level, feeding fibers are available in a 50, 100, 200 or 300 μm diameter featuring unbeatable beam quality in comparison with solid-state lasers. The beam can be switched to any channel from any position within 50ms. A state of the art safety system constantly monitors the position of mirrors, fiber interlocks, scattered light inside beam switch cavities, water flow for optical connectors and other important parameters. We manufacture all of our optical couplers, beam switches and beam splitters as well as process fibers. Process fibers are available in 100, 150, 200, 300, 400, 600, 800 or 1,000 μm diameter with lengths up to 100 meters.
