Optimum focusing of Gaussian laser beams is first discussed by Dickson, who described the change in beam radius under the effect of focusing system parameters. The purpose of this study is to present a formulation for calculating the waist shift under various optimum conditions. Because the variations of beam waist can be measured directly, the waist shift in a focused Gaussian beam is a more practical parameter than the movement of the intensity maximum that is the subject for investigators of the well-known focal shift problem.
