Abstract

We report on the crystal growth, spectroscopic properties and visible laser performance of praseodymium-doped Sr_0.7La_0.3Mg_0.3Al_11.7O₁₉ (ASL) and SrLaGa₃O₇ (SLGM. With 2at.%Pr: ASL, the orange, red and deep red laser have been achieved in plano-concave cavity. The maximum output power of red laser amounted to 267 mW for 1.2 W of absorbed pump power and the slope efficiency reached 27%. For orange and deep red laser, 50 mW and 234 mW maximum output powers were achieved with the same absorbed power of 1.2 W, resulting in slope efficiency of 11 and 24%, respectively
