Spectral analysis of CO2-TE-laser-ablated plasma on
YBa2Cu3O72-x targets demonstrates a very complex spectrum with emission
lines from atomic and ionic species. Plasma temperature is estimated
at different moments in its evolution. A good accordance with the
values achieved by considering an adiabatic plasma expansion is obtained.
Plasma emission intensity is studied as a function of laser pulse
energy and, for the same incident energies, a very reproducible amplitude
is evidenced. Using a hydrodynamic model, plasma parameters are
