Abstract
A diode laser and a laser resonator for a diode laser are provided, which has high lateral beam quality at high power output, requires little adjustment effort and is inexpensive to produce. The laser resonator according to the invention comprises a gain section (GS), a first planar Bragg reflector (DBR) and a second planar Bragg reflector (DBR), wherein the gain section (GS) has a trapezoidal design and the first planar Bragg reflector (DBR) is arranged on a first base side of the trapezoidal gain section (GS) and the second planar Bragg reflector (DBR) is arranged on the opposing base side of the trapezoidal gain section (GS), wherein the width (D) of the first planar Bragg reflector (DBR) differs from the width (D) of the second planar Bragg reflector (DBR).
