Abstract

Using BaTiO₃ crystals doped with cobalt, we have measured the reflectivity of self-pumped phase-conjugate mirrors operating in the total-internal-reflection geometry as a function of wavelength in the range between 633 and 933 nm. We find that for cobalt concentrations above 25 parts in 10⁶, the reflectivity is higher than 50% for all the investigated wavelengths. At a wavelength of 800 nm the reflectivity is independent of incident power over a range of 12 to 600 mW.
