Abstract:
|
Laser radiation at 1.06 µm from a pulsed Nd:YAG
laser was focused onto a multielement YBa2Cu3O7 target in
vacuum and the plasma thus generated was studied using
time-resolved spectroscopic techniques. Line broadening of
the Ba I emission line at 553.5 nm was monitored as a function
of time elapsed after the incidence of a laser pulse on the
target. Measured line profiles of barium species were used to
infer the electron density and temperature, and the time evolution
of these important plasma parameters has been worked out. |
