Zusammenfassung:	A symmetrization device and laser diode system using such a device is shown. The device has adjacent lens components transforming beamlets from a laser diode array. Each lens component has input and output surfaces, each having a profile in the propagation direction of the beamlets and a contour perpendicularly thereto. The profiles of the input and output surfaces and distances therebetween are selected to permute the divergence along the slow and fast axes of the beamlets. The contour of each surface matches the cross-sectional shape of the beamlets thereat.
