US Patent 7800013 Laser device and laser system using same

A laser device (10) includes a first laser source (102) for emitting laser beams with a first wavelength, a second laser source (104) for emitting laser beams with a second wavelength, a dichromic beamsplitter (110), and a flexible light waveguide (112). The dichromic beamsplitter is configured for transmitting laser beams emitted from the first laser source and changing a transmission direction of the laser beams emitted from the second laser source. The flexible light waveguide transmits the laser beams from the dichromic beamsplitter, and the flexible light waveguide has a light-input end (114) and a light-output end (116). The light-input end receives the laser beams from the dichromic beamsplitter, and the light-output outputs the laser beams to a workpiece. A laser system (30) using the same is also provided.
