Twin peak distribution of electron emission profile and impact ionization of ambient molecules during laser ablation of silver target

RC Issac, P Gopinath, GK Varier, VPN Nampoori… - Applied physics …, 1998 - pubs.aip.org
Laser-induced plasma generated from a silver target under partial vacuum conditions using
the fundamental output of nanosecond duration from a pulsed Nd: yttrium aluminum garnet
laser is studied using a Langmuir probe. The time of flight measurements show a clear twin
peak distribution in the temporal profile of electron emission. The first peak has almost the
same duration as the laser pulse while the second lasts for several microseconds. The
prompt electrons are energetic enough (≈ 60 eV) to ionize the ambient gas molecules or …
