Progress in Ultrafast Intense Laser Science XII This volume covers a broad range of topics focusing on atoms molecules and clusters interacting in intense laser field laser induced filamentation and laser plasma interaction and application. The PUILS series delivers up to date reviews of progress in Ultrafast Intense Laser Science a newly emerging interdisciplinary research field spanning atomic and molecular physics molecular science and optical science which has been stimulated by the recent developments in ultrafast laser technologies. Each volume compiles peer reviewed articles authored by researchers at the forefront of each their own subfields of UILS. Every chapter opens with an overview of the topics to be discussed so that researchers unfamiliar to the subfield as well as graduate students can grasp the importance and attractions of the research topic at hand; these are followed by reports of cutting edge discoveries.
