Abstract (EN): Optical third harmonic generation at 1.904, 1.579 and 1.064 ¿m experiments have been performed on thin films fabricated from side chain polymers containing effectively 4-dialkylamino-nitro-benzene, 4-dialkylamino-4¿-nitro-stilbene, 4-dialkylamino-4¿-nitro-diphenylbutadiene, 4-dialkylamino-4¿-nitro-diphenylhexatriene as the side groups. We have measured values of ¿(3) (-3¿; ¿, ¿, ¿) in the range of 0.54 × 10-12 to 7.42 × 10-12 esu, at 1.904 ¿m incident radiation, which are comparable to the nonresonant values found in fully conjugated back-bone polymers [1]. The values of ¿(3) at both 1.904 and 1.579 ¿m change by a factor of 15 as the conjugation length is increased. © 1990.
