Abstract

Diode pumping of a stress-free, Nd(5%at.):KGd(WO4)2, grown by top nucleated floating crystal (TNFC) method, is presented. The diode-pumped laser was operated both in the free-running and passively Q-switched operating modes. Under optimized conditions of resonator and optics, the disk (1.3 mm in thickness), produced at room temperature an efficient free-running, TEM₀₀ output with maximum power of 0.4 W, with 75% slope efficiency and 51% total laser efficiency. The results presented here indicate the potential Nd:KGd(WO4)2 crystals grown by TNFC growth method, as candidates for concentrated, stress free diode pumped microlasers in a large variety of wavelengths, including the eye-safe range.
