Abstract

This paper presents our latest experimental results of welding and cutting of steel and aluminum using a High Power, High Brightness Direct Diode Laser (DDL) upgraded with a Laser-Integrated Dynamic Beam Shaper (DBS). TeraDiode’s DDLDBS laser system transforms the beam distribution from Gaussian-like to Doughnut shape, and a beam parameter product from 4 to 25mm·mrad and doing so in a continuous, real-time manner with very low latency below 10ms. These capabilities unlock a wide range of processing parameters and an overall improved quality for metal cutting and welding while using simplified processing heads. This capability can be applied to DDL from 500W to 8000W power range.
