Vv. Danilov et al., Efficiency of the use of two-photon absorption in impurity liquid crystalsas a mechanism of optical limitation, OPT SPECTRO, 90(3), 2001, pp. 371-374
An analysis is made of the advantages of impurity liquid-crystal systems th
at are associated with the existence of the excitonic mechanism of electron
ic excitation energy transfer in them. Using the two-photon absorption in s
uch systems, one can substantially expand the dynamic range of optical limi
tation. (C) 2001 MAIK "Nauka/Interperiodica".
