摘要：

A Y203 Pressed powder target was ablated by pulses from a XeCl excimer laser, operating at 308 nm, 150 mJ/pulse, almost-equal-to 15 ns/pulse and 20 Hz. Emission spectra from Y* and YO* were recorded as a function of ambient oxygen pressure in the range 10(-5)-4 x 10(-1) Torr, at a peak laser fluence of almost-equal-to 4 J/cm2. A kinetic model is developed to describe the results, and the application to production of laser-deposited high-temperature superconductor thin films is discussed.
