i'm doing some readonly stuff right now and clicked this thread! https://www.osapublishing.org/optica/fulltext.cfm?uri=optica-8-11-1365&id=462661 I only skimmed it quick. this involves reading sentences from the middle of the abstract, from materials and methods, and from the conclusion. here are fun points regarding this random article: - presently described using research-grade femtosecond lasers, optics, etc, because their setup is organised for comparison of approaches, not uses - similarly their paper reportedish 1-200 K/s write speed 1-100 b/s read speed, with pointers for how to develop new setups with MB/s speed. - high density due to 5 degrees of freedom to the artefact written to the transparent medium - other uses in shaping detailed nanomaterials
