Abstract

A diode laser apparatus includes a plurality of laser bars, each laser bar having an emission direction and a beam path. The laser bars are disposed along an arc, the emission directions of the laser bars are directed toward an inside of the arc, and a slow-axis direction of each laser bar is oriented along the arc.
