| Outline of Final Research Achievements |
We developed a pulsed CO2 laser oscillating in the cylindrically polarized modes by means of a Triple-axicon optical resonator. We applied it to the machining of the carbon fiber reinforced plastic (CFRP).
Drilling was conducted by radially, azimuthally, and randomly polarized beams. It was found that azimuthally polarized beam could drill the CFRP plate by 25% smaller pulse energy. On the other hand, both radially and azimuthally polarized beams could cut the CFRP plate faster than randomly polarized beam by a factor or two.
