SUMMARY
The discussion focuses on increasing the divergence of a laser beam using bi-concave or plano-concave lenses. A Gaussian beam's properties dictate that the product of divergence and beam waist remains constant. For instance, to increase a laser beam's divergence from 2 mrad to 10 mrad, the beam waist must be reduced from 2 mm to 0.4 mm. The calculations involve understanding the relationship between beam waist and divergence, which is critical for precise optical design.
