Low-moded laser targets spot welding

The CW low-moded laser suits thin material spot welding. When welding thin materials or where it is preferred that the weld is not visible the Low-moded 200-W laser energy evenly spreads over a wide area, which removes the high intensity peak inherent in single mode beams. 

 

The low-moded laser has a tailored beam (M2 to 4 beam quality/ BPP ≤ 1.4-mm. rad) to suit the application with the right degree of intensity and mode stability delivering a profile to avoid cratering in the spot weld. The CW or modulation rate capability up to 100 kHz creates sub 10-us pulses, and a output variation of
