Southampton, UK - SPI Lasers announces the launch of a new CW low-order mode laser specially designed for thin material spot welding. The laser will be launched at LASER World of Photonics China in Shanghai on March 19, 2013.
Single-mode lasers with high intensity Gaussian beams produce exceptional penetration, which is not always desirable. When welding thin materials or where it is preferred that the weld is not visible from the back, then the new low-order mode 200W laser has proven to be a good solution. The energy is evenly spread over a wider area, which removes the high intensity peak inherent in single-mode beams.
For this laser SPI, has tailored the beam (M2 ~ 4/ BPP ≤ 1.4mm.rad) to suit the application with the right degree of intensity and mode stability, delivering a good profile to avoid cratering or break-throughs in the spot weld.
With CW or modulated (up to 100kHz) modulation capability creating sub 10 microsecond pulses and power output variation of <1%, the laser provides a solution in micro-welding across a range of applications include smart phones, battery contacts, medical devices, and fine connectors.
SPI Lasers is a wholly owned subsidiary of the TRUMPF Group.
