Paper Abstract

Semiconductor lasers are used to an increasing extent in electro-optical systems. The highly divergent emission of the laser is usually collimated into a parallel beam. The properties of the collimated beam are directly related to the properties of emission. The physical origin of far-field distribution, wave aberration, astigmatism and polarization are discussed and related to the properties of the collimated beam. Refractive-index guided and gain-guided lasers are compared with regard to maximum output power, coupling efficiency, wave aberrations, and feedback-induced noise.
