Abstract

The preparation of crack-free Ca(NO3)2∶KNO3 glass samples several centimeters long contained in cuvettes is reported. The mechanical stability of nitrate glasses was improved by adding oxide glass fibers, along with partial tuning of the indices of refraction by addition of Cd2+ ions. Efficient χ(3) frequency conversion processes leading to multicolour emission in the visible region down to 0.4555 µm and near-infrared range are due to multiple anti-Stokes and Stokes shifts observed for 10 mm long Ca(NO3)2∶KNO3 and Ca(NO3)2∶Cd(NO3)2∶KNO3 samples under picosecond excitation. All laser scattering components were identified and attributed to the SRS-active vibration mode ωSRS = 1049–1053 cm−1 of the molecular [NO3]− ions.
