Radially polarized beams can be generated, offering a new beam type for laser cutting. The study presents a three‑dimensional theory of laser cutting. The analysis shows that radially polarized beams yield 1.5–2× higher cutting efficiency than plane P‑polarized or circularly polarized beams for thick metal sheets, and explains the physical limits of plane P‑polarized performance.
The three-dimensional (3D) theory of laser cutting is presented. The cutting efficiency determined by its ultimate parameters at different types of polarization is estimated. The physical reasons for limitations of ultimate cutting parameters at a plane P-polarized beam are displayed. In the case of cutting metals with a large ratio of sheet thickness to width of the cut, the laser cutting efficiency for a radially polarized beam is 1.5 - 2 times larger than for plane P-polarized and circularly polarized beams. The possibility of generating the radially polarized beam is discussed.
