Question

Please, solve each part of the problem. The subject is Lasers.

a) For a 632nm gaussian beam mode, determine the beam waist for a 10 degree divergence angle. b) Calculate the Rayleigh length only equal convex mirrors, design an optimal laser cavity which will c) Using produce a gaussian beam with a waist of 200 um and the smallest beam radius at output mirror. (By design, you must provide both the radius of curvature and distances between the mirrors). the
