Abstract
- Abstract We report on the growth, spectroscopic properties and visible laser operation of Pr3+-doped LaMgAl 11 O 19 (LMA) crystal. The absorption and emission spectra were recorded in visible wavelength range and the decay time of 3P 0 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. Highlights • A Pr:LMA crystal was successfully gown by using the Czochralski method. • Spectral parameters of Pr:LMA crystal were obtained. • Using a blue laser diode as pump source, red and deep red laser were demonstrated from Pr:LMA crystal.
