Picosecond backward-propagating lasing of atomic hydrogen via femtosecond 2-photon-excitation in a flame

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceeding

Abstract

We report on the observation of backward-propagating 656-nm lasing of atomic hydrogen in flame using 205-nm femtosecond laser pulses. It shows a donut-shaped spatial mode and smooth temporal profile, suggesting spatially-resolved measurements in few-millimeters resolution.
