A strong decreasing of the intensity of the inverse 2-pulse, 3-pulse and long lived 3-pulse photon echo was observed when a current pulse passed through the strip evaporated onto the surface of the sample (current pulse was applied before or after the laser pulses). The strip is heated by the current pulse and there is the voltage difference at the ends of the strip. The voltage difference creates instantly the nonuniform electric field in the region of optical excitation so the echo intensity is decreased by the short-lived nonuniform line width rise. The line width rise is differentiated for the distinct type ion sites in the LaF3 unit cell. The strip current-heating gives rise to a phonon pulse. When phonon pulse reaches the optically excited volume it causes the shift of energy levels of Pr3+ ions, effecting a phase accumulation and the echo intensity change as a consequence.
