Description

The authors present the results of characterization of linear absorption and nonlinear refractive index of Au, Ag, Cu and Sn ion implantation into LiNbO{sub 3}. Ag was implanted at 1.5 MeV to fluences of 2 to 17 {times} 10 {sup 16}/cm{sup 2} at room temperature. Au and Cu were implanted to fluences of 5 to 20 {times} 10{sup 16}/cm{sup 2} at an energy of 2.0 MeV. Sn was implanted to a fluence of 1.6 {times} 10{sup 17}/cm{sup 2} at 160 kV. Optical absorption spectrometry indicated an absorption peak for the Au implanted samples after heat treatment at 1,000 C at … continued below

Description

The authors present the results of characterization of linear absorption and nonlinear refractive index of Au, Ag, Cu and Sn ion implantation into LiNbO{sub 3}. Ag was implanted at 1.5 MeV to fluences of 2 to 17 {times} 10 {sup 16}/cm{sup 2} at room temperature. Au and Cu were implanted to fluences of 5 to 20 {times} 10{sup 16}/cm{sup 2} at an energy of 2.0 MeV. Sn was implanted to a fluence of 1.6 {times} 10{sup 17}/cm{sup 2} at 160 kV. Optical absorption spectrometry indicated an absorption peak for the Au implanted samples after heat treatment at 1,000 C at 620 nm. The Ag implanted samples absorption peaks shifted from 450 nm before heat treatment to 550 nm after 500 C for 1h. Heat treatment at 800 C returned the Ag implanted crystals to a clear state. Cu nanocluster absorption peaks disappears at 500 C. No Sn clusters were observed by optical absorption or XRD. The size of the Ag and Au clusters as a function of heat treatment were determined from the absorption peaks. The Ag clusters did not change appreciably in size with heat treatment. The Au clusters increased from 3 to 9 nm diameter upon heat treatment at 1000 deg C. TEM analysis performed on a Au implanted crystal indicated the formation of Au nanocrystals with facets normal to the c-axis. Measurements of the nonlinear refractive indices were carried out using the Z-scan method with a tunable dye laser pumped by a frequency doubled mode-locked Nd:YAG laser. The dye laser had a 4.5 ps pulse duration time and 76 MHz pulse repetition rate (575 nm).
