Abstract:In ophthalmic surgery fs laser pulses are used as a precise and safe cutting tool. At specific processing parameters, however, an interesting phenomenon of unintended periodic structures inside the tissue can be observed. In this study, a transparent polymer served as ocular phantom material for further investigations. A Femtosecond laser with MHzrepetition rate and pulse energies below 200 nJ was used. The size of the durable material change caused by applied fssingle pulses was measured in regard to the puls… Show more
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.
