Paper Abstract

We have measured the reflectivity of self-pumped phase- conjugate (SPPC) mirror as a function of wavelength in the range between 720 nm and 830 nm in 0-degree-cut KNbO3:Ni. This is the longest wavelength for which the SPPC has been observed in KNbO3 at room temperature. We have obtained reflectivities R equals 43% at 725 nm and R equals 1% at 831.4 nm.
