Laser action in LaAlO3:Nd3+ single crystal
Abstract
The spectral and laser properties of Nd3+ doped (1wt%) LaAlO3 single crystal are presented. The energy levels of the Nd3+ ion in the La AlO3 matrix were assigned. The Judd-Ofelt parameters Ω2=1.346, Ω4=4.490, and Ω6=5.168 (all ×10-20cm-2) were evaluated. The absorption σabs and emission σemi cross sections at the respective pumping and emission wavelengths were calculated to be σabs(789.7nm )=2.42×1020cm2, σemi(909nm)=5.02×10-20cm2, and σemi(1080nm)=7.03×10-20cm2. Continuous-wave laser action at 1080nm in LaAlO3:Nd3+ was obtained.
