A diode laser module emitting 1.4 kW optical in-pulse power near 780 nm optimized for high (≥ 10%) duty-cycle operation in a micro-channel free design is presented. With full collimation, a beam quality with a nearly symmetric M2 of 205 × 295 (vertical × horizontal direction) for a wide range of pulse widths is found.
