Abstract
Using a time resolved Z-scan technique, the authors distinguished elec tronic (population lens) and thermal nonlinearites. The first measurem ents of the polarisability difference Delta alpha between excited (F-4 (3/2)) and ground (I-4(9/2)) states of Nd+3 ions in fluoride glasses a re presented. A value of Delta alpha similar or equal to 1.6 x 10(-26) cm(3) was obtained in fluorindate glass and Delta alpha < 0.2 x 10(-2 6) cm(3) was estimated for ZBLAN.
