Periodic anharmonic modulation of output intensity is studied for semilinear coherent oscillator with photorefractive crystal that possesses two types of movable charge carriers. The pulse amplitude and modulation frequency are shown to depend considerably on grating spacing of photorefractive grating. We calculate these dependences within the model proposed earlier [A. Shumelyuk, A. Hryhoraschuk, S. Odoulov, Phys Rev. A, 72, 023819 (2005)] and show satisfactory agreement with the experimental data.
