In order to make quantitative predictions of the output powers and energies from a laser it is necessary to know the value of the stimulated emission cross section. Conversely by measuring the output power or energy it is possible to calculate the cross section. Cross sections for the 4F(3/2) to 4I(11/2) of Nd doped materials (Nd:glass, Nd:YAG), Nd:SeOCl2 although a literature search by the authors failed to reveal any published figures for Nd:CaWO4. This paper reports a measurement of the 4F(3/2) to 4I(11/2) cross section in Nd:CaWO4 using a method which Edwards first applied to Nd glass materials. The crystal investigated was a Na-compensated crystal grown by AEI (Nd concentration nominally 1 at,%) cut in the form of a cylindrical rod 50mm long, 6mm across, with the c-axis parallel to the cylinder axis. The cross section measured is that of the sigma-polarised emission at 1.065µm since the sigma spectrum and axial spectrum are identical.
