The large nonlinear absorption coefficients which range from 11 to 20 cm/GW was determined using standard Z-scan technique. The photodarkening in the samples were observed which suggested that they can also be useful for inscribing Bragg gratings using green lasers of moderate power.4694-4696engAntimonyLaser pulsesLead compoundsLight absorptionNonlinear opticsPhotochromismNonlinear absorptionsGlassArtigo10.1063/1.1529310Acesso aberto2-s2.0-00374492772-s2.0-0037449277.pdf2998503841917815
