The effect of doping and processing conditions on the optical performance of Rh:BaTiO<sub>3</sub>
We demonstrate the advantages of using high levels of rhodium (2000-3200 ppm) to dope barium titanate for achieving finite absorption coefficients (0.36 /cm), high two-beam coupling gain (11.5 /cm) and acceptable response time (7s) at 1.06 µm. We also report on the mass spectroscopy measurements on...

| Summary: | We demonstrate the advantages of using high levels of rhodium (2000-3200 ppm) to dope barium titanate for achieving finite absorption coefficients (0.36 /cm), high two-beam coupling gain (11.5 /cm) and acceptable response time (7s) at 1.06 µm. We also report on the mass spectroscopy measurements on Rh:BaTiO<sub>3</sub> samples indicating a small segregation coefficient for rhodium (below 0.01) and the presence of a relatively large concentration (6000 ppm) of intentionally added strontium. |
