Miyachi Unitek Corporation (Monrovia, CA) has released its new LF Fiber Laser Welding Systems, specially designed for fine micro welding. The LF handles focused spot sizes down to 10 microns, and offers control of pulse width and peak power. The laser is available in either single-mode or multi-mode options.The LF laser features an internal air-to-water cooling mechanism, which ensures power and pulse-to-pulse stability, irrespective of the ambient air temperature. It can be operated in either pulsed or continuous wave mode, and offers features necessary for control of the weld, including pulse shaping. The control interface can be integrated into the laser or provided separately for workstation integration. The LF laser can also be integrated to a motion platform, including both stage and gantry systems, as well as scan heads.
