摘要:
Pulsed laser technologies with Long (LPL Irradiation), Short (SPL Scribing) and Ultra-Short (USPL Ablation) pulse duration can be used on SiFe Grain Oriented Electrical Steels (GOES) to refine the domains and reduce the power loss. The corresponding physics related to the magnetic structure is still a subject of research. This paper identifies separate characteristics responsible for the domains structure and the magnetization properties in a GOES sheet processed with the three laser pulses. Magnetic domains based properties are identified thanks to an average dynamic mu-nu c-? model, the Tensor Magnetic Phase Theory (TMPT), magnetic measurements/observa-tions with the Single Sheet Tester (SST) and the Magneto-Optical Indicator Film (MOIF) technique.
