The ANTAUS microjoule ultrafast fiber laser system features high pulse energy along with fast repetition rate, which is an ideal combination for subtle material processing applications, as well as for many kinds of scientific research. Unlike most of the competition, the ANTAUS features short pulse duration and near-perfect AC trace with almost no pulse pedestal. The system is an all-Yb-doped-fiber oscillator + amplifier with a free-space final pulse compressor. Such design architecture ensures greater stability and true turn-key operation with no maintenance as well as the highest possible output pulse energy and spatial beam quality. The laser is already being used by our customers as an OEM laser source in ophthalmology (in LASIK-type eyesight correction apparatus), as well as for THz studies, surface modification, two-photon polymerization techniques and many more.
