Metal cutting and other important laser machining seam width or to cut any changes happened cross-section are very sensitive. Cut the quality depends on the relative to sew the light polarization direction cutting direction. As shown in figure 1 below.

According to the existing theory, only when start cutting, focus on the light will incident in the way is to illuminate the surface of workpiece. Once cut seam in form, beam incident Angle Θ a larger metal cutting surface, as shown in figure 2. Relative to the metal cutting angled light polarization in "s than the light polarization p is easier to the surface reflection, caused the cutting quality of the differences in different cutting direction.

Introduced in beam transmission path a quarter wave (90 °) reflex phase delay garden a polarizer can eliminate seams change, cut because it will line for circularly polarized light conversion polarized light. Circular polarization direction in any beams by the same amount of s polarization and p polarization of composition, so in all the axial will have the same ingredients polarization, no matter how cutting direction, will with uniform mode to remove material. Such as the left picture shown.

Fig.03 shows, will line with polarized light polarization direction incident plane into 45 °, 45 ° according to the incident in reflex garden polarization mirror reflected light, will be transformed into garden polarized light.

The phase delay should be used for according to the basement laser power to choose. We have many basal materials are available, including water-cooled copper. You can also choose one of 16 points one-eighth and phase delay of wave tablet reflex garden a polarizer design, select for 10.6 outside of apms m wavelength of peak wavelength of other design.
