Abstract
Organic impurity systems which exhibit effect of photoburning of persistent spectral holes have several interesting spectroscopic and prospective practical applications [1, 2]. A CW holographic technique for detecting of narrow hole shapes in thin polymer films doped with organic dye molecules can be used in combination with a variable-strength applied electric field to obtain information about the homogeneous line shapes and symmetry properties of the impurity centres [3]. This method serves also as a demonstration of the possibility of parallel optical computing [4].
