28 February 2014 Optic axis dispersion in double tungstate crystals and laser operation at 2 μm
Author Affiliations +
Measurements of the optic axis dispersion in double tungstate crystals have been performed from 400 nm to 1.58 μm. The measurements have been performed on KGdW, Nd-doped KGdW and Ho-doped KYW crystals. The samples were longer than 1 cm and had a good optical quality. The absolute angle reference was set using the Laue method. This reference allows us to compare more accurately our measurements with the calculations made using refractive index values found in literature. The difference observed between calculated values and measurements is significant. The relative dispersion looks similar for all double tungstate crystals tested. Furthermore first results of Holmium doped KYW laser operation along this axis will be shown.
