This book features chapters based on lectures presented by world-leading researchers of photon
science from Russia and Japan at the first STEPS Symposium on Photon Science held in Tokyo in
March 2015. It describes recent progress in the field of photon science covering a wide range
of interest to experts in the field including laser-plasma interaction filamentation and its
applications laser assisted electron scattering exotic properties of light ultrafast imaging
molecules and clusters in intense laser fields photochemistry and spectroscopy of novel
materials laser-assisted material synthesis and photon technology.
