Nd(3+) beta'' alumina platelet laser

Pulsed as well as cw laser action has been observed in a new host material for Nd(3+) ions, Na(+) beta'' alumina. The unusual characteristics of the material and its known physical properties are briefly described. Absorption spectra, fluorescence lifetime, laser-pulse shape, and peak emission wavelength are presented as experimental evidence, and comparisons are made with other Nd(3+) host materials. Some exciting new possibilities for integrated-optics applications are explored.
