Abstract
Single crystals of Er3+- and Nd3+-doped KLiYF5 have been grown by top-seeded solution growth. Large concentrations of rare-earth substituents on the Y3+ Site are possible in this crystal on account of the orientation and packing of adjacent Y-F-8 coordination polyhedra. Odd-parity distortions of the rare-earth site result in large absorption and emission cross sections for both Er3+ and Nd3+. The absorption, emission and lifetime spectroscopy of Er3+:KLiYF5 are reported. Applications of Er3+:KLiYF5 and Nd3+:KLiYF5 as gain media in GaAlAs diode-pumped laser devices are discussed in terms of the spectroscopy of these materials. Preliminary experiments connected with such applications are reported. Whilst pumping the materials close to 800 nm, low-threshold, high slope efficiency continuous wave laser action was achieved at 1.05 mu m in Nd3+:KLiYF5 and strong upconversion photoluminescence close to 550 nm was observed in Er3+:KLiYF5.
