Multi Transverse Mode Laser Diode Beam Manipulation Optics

Abstract

The method of calculating the spot size of a collimated or focused beam of multi TE mode laser diodes is discussed. Fiber delivery and micro prism shaping of multi TE mode laser diode beams are briefly described. Multi TE mode laser diode beams are of high power and mainly used in illumination type of applications where less accurate beam manipulation is required. Yet, multi TE mode laser diode beams have unique characteristics of both a Gaussian beam and a geometric beam, the collimation and focusing of multi TE mode laser diode beams should be analyzed differently.
