Vn. Lisin et al., MODULATION OF PHOTON-ECHO POLARIZATION BY AN ELECTRIC-FIELD - PSEUDO-STARK SPLITTING IN LAF3-PR3+, Laser physics, 6(1), 1996, pp. 195-200
The change of photon echo polarization by an external electric field i
s investigated. An electric field removes the equivalence of three sub
groups of ions differing in the directions of the local symmetry axes,
so that the polarization and the intensity of a photon echo are chang
ed. For the first time the Stark shift 32 +/- 0.5 kHz/V cm(-1) and the
difference of electric dipole moments 0.006 D for the H-3(4)(Gamma(1)
)P-3(0)(Gamma(1)) transition in LaF3:Pr3+ are found experimentally.
