Active Multipass Geometry Boosts Pulse Energy

Facebook X LinkedIn Email
Scientists from the University of Konstanz and from Trumpf Laser GmbH + Co. KG in Schramberg, both in Germany, have achieved pulse energies of more than 13 μJ from a thin-disc laser operating in air. These ultrashort pulses have applications in micromachining and in experimental physics as well as in the direct pumping of parametric devices. This 3-D perspective of a thin disc demonstrates the multiple passes of the laser mode. Courtesy of Trumpf Laser GmbH & Co. KG. The Yb:YAG disc is 60 μm thick and 10 mm in diameter and has good thermal management and optical linearity....Read full article
