Abstract

Stimulated emission as a result of the inter-Stark transition in the 1-μm ⁴F_3/2→⁴I_11/2 channel of Nd³⁺ ions was excited for the first time in an acentric disordered Sr_xBa_1-x(NbO₃)₂ (x≈0.6) crystal. The low-threshold lasing of this crystal at the 1.0626 μm wavelength was accompanied by diffuse intracavity generation of the second harmonic.
