Abstract

On our way to industrial high power lasers up to 40 kW, we have successfully realized the first step, i.e., the development of an extremely compact 12 kW CO₂ laser with a very high beam quality. The laser is capable of high frequency pulsing up to 100 kHz with consistent mode quality over the full power range from 5 - 100%. Detailed beam quality analysis is presented. In its 10 kW version, this laser has a beam quality better than K equals 0.35. This unmatched focusability permits high quality deep penetration welding and ultra high power cutting applications. Current work concentrates on a completely new 20 - 30 kW laser, which should show similar characteristics as the 12 kW laser with regard to spatial and temporal beam quality. Furthermore, with the foot-print of the laser head being only 4.5 m², this system is significantly smaller than those that are currently available, which is a prime consideration for expanded industrial use.
