Nonlinear optical properties and optical limiting behavior of antimony and lead oxyhalide glasses were studied using laser pulses of 80 ps at 532 nm. The standard Z-scan technique was used to determine large nonlinear absorption coefficients which range from 11 to 20 cm/GW, using intensities of 100 MW/cm2. Photodarkening was observed when intensities larger than ≈200 MW/cm2 were incident on the samples.

“…Although AG glasses have been discovered long time ago, [5][6][7] only recently techniques were developed that allow the preparation of good optical quality samples. [8][9][10] Up to the present time the characterization of the nonlinear ͑NL͒ optical absorption and NL refraction of AG has been limited to the wavelengths of 800 and 532 nm. Large NL refractive index, low two-photon absorption coefficients, and ultrafast response ͑faster than 100 fs͒ at 800 nm were reported.…”

We report measurements of the nonresonant nonlinear refractive index n2 in antimony glasses at telecom wavelengths. The measurements were performed using the Z-scan technique with a 130fs pulsed laser operating at five wavelengths in the range of 1400–1600nm. Values of n2≈10−15cm2∕W were measured and a negligible two-photon absorption coefficient (<0.003cm∕GW) was estimated for all glasses compositions. The samples present a good figure of merit for ultrafast all-optical switching.

“…Antimony oxide based glasses have been the subject of interesting studies in the last years [1][2][3][4][5][6][7][8][9][10][11] and have been claimed to be useful in important fields of the materials science, such as photonics [12][13][14][15][16] and plasmonics [17][18][19] . These materials present low phonon energy (~600-700 cm -1 ) due to low energy stretching vibrations of Sb-O-Sb band 20,21 , high linear and nonlinear refractive indexes [3][4][5] and the possibility of modulation of their optical constants, (refractive index, n, and absorption coefficient, ) under laser irradiation 22 what make them promising materials for 3D optical storage 23,24 as well as, for holographic data storage 25 .…”

(x) , with composition 0.1  x  0.5 (in mol %) were studied. The structural changes due to the replacement of Sb 2 O 3 by WO 3 have been investigated. It was found that the incorporation of WO 3 enhances the thermal stability of the glasses against devitrification when compared to the binary Sb 2 O 3(0.6) -SbPO 4(0.4) composition. The connectivity of the network increases with WO 3 content which is consistent with the high values of the glass transition temperature. Raman studies suggest that WO 3 incorporation breaks the primary network, constituted by antimony oxide, while a second network containing WO 6 octahedral units is built up. Thermal and structural properties were evaluated by differential scanning calorimetry, infrared and Raman spectroscopies, 31 P Magic Angle Spinning NMR and X-ray absorption near edge structure (XANES) at L 1 and L 3 edges of Sb and L 1 edge of W atoms.
