METHOD FOR LASER CUTTING METAL PLATES

摘要

A laser cutting method for complex slotted spinneret capillaries wherein a multi-mode laser beam is reduced to predominantly a single mode and focussed above the work piece. The predominantly single mode is a TEMoo mode. By recutting the capillary slots with the laser, metal oxide particles condensed from the vapor phase and resolidified molten metal on the walls of the slots are removed.
