High Power Laser Beam Combiner

An all fiber signal combiner is an essential component to break through the incoherent beam output power limitation of fiber laser power.

High power laser beam combiner.

High power laser combiners lightel s combiners are available with modified packaging to combine several solid state or fiber lasers into a multimode transmission fiber to achieve a laser power output in the range of several kilowatts to 10 kilowatts. Visible light source can be added to the output delivery fiber for guidance in the machining process. An all fiber 3 1 power combiner with each input port being capable of handling comparatively high power is demonstrated in this paper. Over the last decade high power fiber lasers have gained substantial market share in industrial applications such as marking metal cutting and welding due to their excellent output beam quality and high wall plug efficiency.

It features exceptional optical characteristics. Three self made yb doped fiber lasers with a center wavelength of 1080 nm and maximum output power of 4 5 kw are applied in the experiment. These devices can combine 2 pump lasers and 1 signal channel into one fiber and create a high power pump laser source delivering the combined power for applications. Both of the simulation and experiment are investigated.

Dk photonics 2 1 x1 multimode pump and signal combiner is designed for high power applications. Coherent beam combiner yields 100 w of fiber laser power.
