Abstract
Laser diode beam propagation characteristics, the collimating and focusing behaviors and the M 2 factor are discussed using equations and graphs. Thin lens equation modified to be applicable for laser beams is introduced. An example about collimating and focusing a laser diode beam is presented. Raytracing technique is briefly discussed.
