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 all kinds of scientific research. The system is an all-Yb-doled-fiber oscillator + amplifier with a free-space final pulse compressor. Such design architecture ensures greater stability and real turn-key operation with no maintenance. The system does not require any water-cooling. The repetition rate of the system may be modulated via an optional AO pulse picker.

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.
