The effect of reflection and 2K gratings on the efficiency of photorefractive self-pumped phase-conjugate mirrors (SPPCM’s) was studied theoretically and experimentally. Semilinear SPPCM’s of BaTiO3 are used as an example. It is shown with numerical calculations that in normal experimental configurations all these gratings are helpful for the performance of the SPPCM’s. With a 45°-cut BaTiO3:Ce we determined experimentally the variation of reflectivity of a semilinear SPPCM when the crystal’s gain coefficients that correspond to the gratings were changed by variation of the cavity length of the semiresonator in the SPPCM. The experimental results verified the theoretical predications. The validity of our conclusions for SPPCM’s with other photorefractive crystals such as KTaxNb1−xO3 and (KyNa1−y)2Z(SrxBa1−x)1−ZNb2O6 is discussed.
