O. Musset et al., Laser emission under flashlamp pumping of a new crystal: Nd-doped strontium-lanthanum-aluminate (Nd : ASL), APP PHYS B, 68(2), 1999, pp. 181-185
Nd-doped strontium-lanthanum-aluminate (Sr1-xNdyLax-yMgxAl12-xO19) is a new
material, tunable in the 1-1.1 mu m band. We present the first results of
pulsed laser emission of this crystal under flashlamp pumping. We obtain a
slope efficiency of 3.3% with a maximum average power of 40 W at 40 Hz in f
ree-lasing regime. Nd:Cr codoping of ASL is also tested, but with much lowe
r efficiency.
