Laser photolysis of Er organometalics impregnated into Vycor glass with supercritical CO 2

Studies of UV laser photolysis of Er organometallics (ErFOD) impregnated into porous Vycor glass in supercritical CO2 was performed, aimed at developing a new approach to glass microstructuring. It was revealed that quantum yield of UV laser photolysis increases with laser intensity. Efficiency of ErFOD photodegradation for the XeCl laser irradiation is almost two orders of magnitude higher than that for KrF laser. The effect of light scattering in the porous glass on the focusing of laser beam was also revealed.© (2004) COPYRIGHT SPIE--The International Society for Optical Engineering.
