The crystal of Nd3+:KGd(WO4)2 with the size of φ20 mm×60 mm was grown by using the modified CZ. method The absorption and emission spectra in the directions of a,b and c axes were measured, the result shows that the intensity of absorption and emission spectra in the direction of a axis is the strongest Therefore, the direction of a axis is the most suitable for laser experiment The intracavity stimulated Raman scattering frequency self-conversion of the 1352.5 nm laser line was obtained under short-pulsed longitudinal pumping at 600 nm. The wavelength is eye-safe at 1539.5 nm and the conversion efficiency was 1.26%. A laser output of 125.5 mJ at 1.067 μm was obtained from the excitation of a Xe lamp. Compared with the YAG-Nd3+ laser crystal, which was performed the same laser experiment at the same conditions, NdhKGd (WO4)2 has the advantages of lower laser threshold and higher efficiency as well as the polarized laser output Therefore, it is expected that Nd3+:KGd(WO4)2 crystal will be very useful in the miniature laser.
