Using BaTiO(3) 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 10(6), 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.
使用掺钴的钛酸钡（BaTiO₃）晶体，我们测量了在全内反射几何结构中工作的自泵浦相位共轭镜的反射率，该反射率是波长在633至933纳米范围内的函数。我们发现，对于钴浓度高于百万分之25的情况，在所有研究波长下反射率均高于50%。在800纳米波长下，反射率在12至600毫瓦的入射功率范围内与入射功率无关。
