Laser beam shaping for battery welding | Laser Focus World- laser beam shaping ,Sep 22, 2021· Laser beam shaping has proven to be a valuable tool in the laser process engineer’s toolbox. The innovative combination of beam shaping and single-mode beam quality in a single laser source adds the processing flexibility to control keyhole stability and weld quality while maintaining the high intensity necessary for welding battery materialsLaser beam shaping based on amplitude-phase control of a ...A new technique is suggested for the generation of laser beams with an intensity profile specified. The technique is based on the coherent combining of radiation of a fiber laser array with adaptive control of the power and phase of Gaussian subbeams with plane wavefronts. The power and phase of the subbeams are determined for each intensity profile specified in the far …

The output of a laser diode diverges in an asymmetrical pattern, making collimating the beam a challenge. Cylindrical lenses can be used to circularize the beam. Consider a laser diode with beam divergence of θ 1 x θ 2 = 10°x 40°. Any attempt to collimate this beam with spherical optics would result in collimation in one direction only, with a diverging or converging beam in the …

Sep 07, 2020· Conduction welding often uses a so-called “flat top” beam. “A typical spot size is 600 microns or larger,” Victor said. “But to weld in conduction mode, even 600 microns is too small, so often the process engineer moves the beam out of focus to achieve a diffuse beam shape.”. A laser focus point centers around the beam’s waist ...

We consider four families of functions--the super-Gaussian, flattened Gaussian, Fermi-Dirac, and super-Lorentzian--that have been used to describe flattened irradiance profiles. We determine the shape and width parameters of the different distributions, when each flattened profile has the same radius and slope of the irradiance at its half-height point, and then we evaluate the …
