This book is dedicated to an experimental work on the molecular dynamics following the interaction with laser field. This research project was carried out using high intensity pulsed lasers with near-IR central wavelength. Cold target recoil ion momentum spectroscopy technique - also known as "Reaction Microscope" - and pump-probe approach were used to initiate a dynamics in some diatomic and triatomic molecules (deuterium, hydrogen, nitrogen, oxygen, carbon monoxide and dioxide) with a laser pulse and interrogate it with another pulse. Coulomb explosion imaging and coincident measurement...
