Impurity enhanced self-pumped phase conjugation in the near infrared in 'blue' BaTiO<sub>3</sub>
Photorefractive self-pumped phase-conjugation is examined at near-infrared wavelengths using doped 'blue' BaTiO<sub>3</sub>, and reflectivities are reported as high as 76% between 720 nm and 1004 nm due, as is believed, to a backward stimulated photorefractive scattering mechan...

Summary: | Photorefractive self-pumped phase-conjugation is examined at near-infrared wavelengths using doped 'blue' BaTiO<sub>3</sub>, and reflectivities are reported as high as 76% between 720 nm and 1004 nm due, as is believed, to a backward stimulated photorefractive scattering mechanism. Data also suggests that it is possible to stabilise the phase-conjugate reflectivity by vibrating the crystal. |
