ABSTRACT:
A laser cutting method for complex capillaries wherein a multi-mode beam from a solid-state is reduced to predominantly a single mode and focused to a spot about 40 microns in diameter. The laser is focused about 0.2 to 0.3 mm 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.
