Y{sub 2}O{sub 3} pressed powders were ablated by pulses from a XeCl excimer laser, operating at 308 nm, 150 mJ/pulse, {approx}15 nsec/pulse and 20 Hz. Emission spectra from Y* and YO* were recorded as a function of ambient oxygen pressure in the range 10{sup {minus}5} -- 4 {times} 10{sup {minus}1} Torr, at a laser fluence of {approx} 4J/cm{sup 2}. A kinetic model is developed to describe the results, and the application to production of laser-deposited high-temperature superconductor thin films is discussed. 13 refs., 4 figs.
