Which optical effect increases with laser beam divergence?

💡 Explanation

Increased laser beam divergence causes higher speckle contrast because interference patterns become more complex due to broader range of angles. Therefore, speckle becomes more pronounced, rather than Raman scattering or Bragg diffraction which is limited by material properties.
