We have observed that it recovers within 300 ms after the excitation laser pulse is gone, this gave a constanttime of 75 ms. By estimating the optical electric field value of the laser pulses used in our experiments, we can compareour results with those obtained in polyurethane elastomers studied by the electrostriction technique [1,9] 2006 artículo científico 1665-3521 https://www.redalyc.org/articulo.oa?id=94219306 en http://www.redalyc.org/revista.oa?id=942 Superficies y vacío application/pdf Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C.
