摘要：
Strong, permanent surface-relief and refractive index gratings are written in lead-silicate glasses by irradiation with the output of a pulsed KrF excimer laser (248 nm) through a phase mask. Diffraction efficiencies as high as 10% are obtained. The diffraction efficiency of the refractive index grating after removal of the surface-relief grating shows that a very large photoinduced refractive index change (Delta n(0) = 0.09+/-0.02) is obtained.
