Abstract
We report on the growth, spectroscopic properties and visible laser operation of Pr3+-doped LaMgAl11O19 (LMA) crystal. The absorption and emission spectra were recorded in visible wavelength range and the decay time of 3P0 manifold was measured to be about 34.5 μs at room temperature. Using an InGaN laser diode as pump source, continuous-wave laser operation of Pr:LMA crystal have also been demonstrated in red at about 645 nm and deep red at about 725 nm, which provide new linearly polarized sources for various potential applications.
