(256) 824-2898 email: [email protected] Office Hours: Tues/Thurs 2-3PM JDW, ECE Summer 2010 Chapter 12: Stable Laser Resonators and Gaussian Beams • Stable curved mirror cavities • Properties of Gaussian beams • Properties of real Laser beams • Propagation of Gaussian beams using ABCD matrices Cambridge University Press, 2004 ISBN-13: 9780521541053 All figures presented from this point on were taken directly from (unless otherwise cited): W.T. Silfvast, laser Fundamentals 2 nd ed., Cambridge University Press, 2004. Chapter 12 Homework: 3,6,7,9,11 Stable 2 Mirror Cavity Designs ABCD Matrix Elements for Transmission and Reflection ABCD Matrix Elements for Transmission and Reflection ABCD Matrix • Consider a beam traveling from r1 to r2. The beam travels at an angle θ . Assuming no index change or reflection, then the value θ 2 = the incident angle • This can be written in matrix form as • Where the ABCD translation matrix is ABCD Matrix for lenses • A ray passing through two lenses of focal length f1 and f2 can be written as •...
