The Hashemite University Physics Department Second Semester 2021 2022 Phys. 464 "Laser Physics" Makeup Exam. April 26, 2022 Instructor: Professor Wael Salah Q1. Suppose a Gaussian laser beam with wavelength 2o and total power P is focused on the plane z = 0 with a waist 00. The beam is directed at a target a distance d away. Show that the value of at which the peak intensity on the target is maximized 2 d is 0o = TT Q2. A ray initially parallel to the optical axis elements as shown in the Figure optical axis in the 171 propagat
