Fiber output hybrid laser system

A fiber output hybrid laser system, comprising:

• at least a blue ray laser model, emitting a blue ray laser beam through a blue ray optic fiber;
• an infrared optic fiber laser module, emitting an infrared laser beam through an infrared optic fiber;
• a fiber bundle, which being used for embedding the blue ray optic fiber and the infrared optic fiber, and emitting an output light beam through an output optic fiber;
• an output optical assembly having a collimating lens and a focusing lens arranged at front and back, wherein the collimating lens is used to form the output light beam into a collimated parallel beam;
• and the focusing lens will make the passing parallel beam generating focal points of two wavelengths, which are a first focus and a second focus;
• and
• the output light beam generated by the output fiber, including the blue ray laser beam and the infrared laser beam which are coaxial and coincident to emit light, and the BPP of the blue ray laser beam and the infrared laser beam are both less than 10 mm*mrad;
• and through the adjustment of the focusing lens, the first focus of the blue ray laser beam will be formed on the surface of a material to be processed, and the second focus of the infrared laser beam will be penetrate into the material to be processed, and the distance between the first focus and the second focus is 1-3 mm, so as to obtain the best welding and cladding effects.
