Applying an femtosecond-pulse burst instead of an energetic single pulse holds the promise to significantly improve materials processing at highest average powers. AFS ultrafast fiber-laser systems can be operated in a burst mode with negligible variation of pulse duration over the burst and with a flexible pulse structure.

As a part of AFS leading-edge fiber laser technology, the fast pulse-switching feature provides an optional extension of the laser‘s capability.
Single-pulse selection can be achieved up to 10 GHz repetition rate with this patented technology. Full control over the pulse sequence is guaranteed on both their occurrence and their amplitude, which can be adapted to the customers needs. Most important, the ultrafast modulator works at highest average power levels without any detrimental effects on the laser characteristics.
