Abstract
An arrangement for converting diverging polarized laser emission from a semiconductor laser into a convergent beam includes two optical lenses and an optical isolator formed of a Faraday rotator and at least one polarizer arranged in the beam path of the laser emission. The lens which lies farther from the semiconductor layer is a component of the Faraday rotator and is formed by a plano-convex lens having an curved side facing the semiconductor laser.
