The JK400FL from GSI Group has all the advantages already demonstrated by the other units in the range, but with increased power and performance. Capable of faster processing speeds and the capacity to cut and weld thicker materials, these improvements make for a highly efficient machine that is both time saving and cost effective.
According to the company, applications laboratory analysis shows superior performance over traditional laser processing with increased cut quality and speed, lower dross levels, and smooth spatter free welds. The stable single resonator and in-built pulse shaping capability are other features that make this laser stand out from the crowd. Despite the increased power GSI has kept the JK400FL compact and simple. The absence of free space optics means there is a little or no maintenance required.
The JK400FL offers exciting new power levels to the JK fiber laser range. Using the same single resonator platform as the rest of the range ensures a more rugged design than the use of amplifier stages to increase the CW power level. The single mode output fiber delivers a near diffraction limited beam that is consistent and stable across the whole power range. At maximum power the wall plug efficiency is better than 25%, leading to economic operation and low environmental impact.
