Starting with the expression for intensity, how that the point (p = 0, z = 0) is where a Gaussian beam has the maximum intensity. Plot the variation of intensity around this point as a function of p and z either together or separately. FYI- dielectric particles can get trapped in region of maximum intensity, and we use fo- cussed Gaussian beams to trap such particles.
