Abstract:High-precision processing of materials with ultrafast laser pulses is drawing increasing attention as laser sources are finally catching up with industry requirements. In particular, very rapid progress has been achieved in ultrafast fiber lasers, which are popular as a result of their highly repeatable, environmentally robust performance, compact size and possibility to reach high average powers. Meanwhile, our understanding of the rich physics of ultrafast laser-material interaction remains incomplete, where… Show more
“…f burst * n pulses = f e f f ective (1) This way, we can use all the advantages of a high repetition rate laser without the need to go to high powers. The effectiveness of burst-mode operation was demonstrated for material processing by enabling ablation cooled regime, which was discovered in our group in relation to laser material processing [3]. We have developed specialized fiber laser systems which use synchronized pulsed pumping to supress ASE and achieve high pulse energy at low burst repetition rates [4].…”
Fiber lasers which operate in burst-mode where densely spaced pulses occur inside bursts repeated at much lower repetition rates can be valuable tool for sensing and imaging. We introduce such lasers and propose possible applications.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
