WebApr 14, 2024 · The beam shaping diffuser produces a uniform beam profile by diffusing the laser beam, which distributes the laser energy over a wider area. The diffuser achieves this by creating tiny variations in the beam’s phase, resulting in a specific beam profile, such as a flat-top or Gaussian profile. WebDuring the transition from the Gaussian to Annular distribution, an interesting flat-field intensity profile can be observed in Figure 4C when Dn equals to 0.0005. This indicates that CDF can be probably utilized to generate flat-top beams. FIGURE 4 FIGURE 4. (A) Theoretical calculated beam quality M 2 under different dip depths.
