Abstract

We modified the theory of the holographic current, describing both the steady-state and the transient contributions and accounting for the parameters of the measurement circuit. In the model of the transient photocurrent we connected the observables of the steplike modulation experiment with the carrier transport parameters such as carrier diffusion and screening length, carrier effective lifetime, and Maxwell relaxation time. Experimentally, we have shown that theoretically predicted dependences of the photocurrent amplitude and relaxation time on the grating period, the light intensity, and the depth of the modulation were observed not only in the photorefractive Sr1-xBaxNb2O6 and Bi12TiO20 crystals but in Er-doped YSGG laser crystals as well.
