Time-resolved emission spectra following the 193-nm photoablation of CuO, BaO sub 2 , Y sub 2 O sub 3 , and YBa sub 2 Cu sub 3 O sub 7 minus x in vacuum and oxygen

Gated diode array spectra were taken after the photoablation of CuO, BaO{sub 2}, Y{sub 2}O{sub 3}, and YBa{sub 2}Cu{sub 3}O{sub 7} in vacuum and oxygen. An ArF excimer laser (193 nm) was used for photoablation. The spectra were resolved on a microsecond time scale. Emission from ions, atoms, and mol...
