Sr_xBa_1-x(NbO_3)_2:Nd~3+ ferroelectric as a new nonlinear laser crystal: continuous-wave one-micron stimulated emission (~4F_3/2→ ~4/_11/2) and diffused self-frequency doubling

摘要

For the first time, the generation of stimulate emission on a one- micron inter-Stark transition of the (~4F_3/2→~4/_11/2) channel of Nd~3+ ions in an acentric disordered Sr_xBa_1-x(NdO_3)_2:Nd~3+(x=0.6) was obtained. The corresponding low-threshold lasing at a wavelength of 1.0626μm was Accompanied by the diffused intracavity second-harmonic generation.
