Abstract

Lasers working on high lanthanide concentrated crystals like tetraphosphate and pentaphosphate has been a subject of investigations in recent years. In this paper we report a preliminary investigation of spectroscopic and laser properties of LiPrP₄O₁₂ crystal. We have measured absorption and emission spectra of the crystal and fluorescence decay times at the ³P₀ level. On the basis of results of the measurements it has been found that the Pr³⁺ ion has two different positions in the crystal.
