Infrared Laser Materials.
Abstract
Neodymium-doped yttrium orthoaluminate is investigated for use as a high-efficiency optically-pumped infrared laser material. The growth of high optical quality crystals was studied and growth parameters including pull and rotation rates, atmosphere, thermal ambients, and annealing are discussed. Measurements of hardness and the distribution coefficient of Nd3+ in YAlO3 and the presence of scattering sites and the tube effect are described. Several possible sensitizer ions for Nd3+ are considered and the optical spectra of cerium and vanadium in YAlO3 are reported. Laser rods containing 1 percent and 3.2 percent Nd were prepared and tested in long-pulse and cw laser operation. The results from these b-axis Nd:YAlO3 rods are compared with those obtained from Nd:YAG. (Author)
