Materials Processing Characteristics of a 2kW Class High Power Density Direct Diode Laser System

摘要

A 2kW class high power density direct diode laser materials processing system was developed and its processing characteristics were examined. By using a wavelength and polarization coupling method, an output power of over 2kW, abeam diameter of 0.96mm and a power density of 235 Kw/CM~2 WERE ACHIEVED AT THE FOCAL POINT. The processing characteristics of the high power density direct diode laser were evaluated for stainless steel and mild steel.
