Abstract: A single-mode, cw stimulated emission of Nd³⁺ ions (through the ⁴F_3/2→⁴I_11/2 channel) has been excited efficiently (at an efficiency up to 30%) in nonlinear trigonal LaBGeO₅, La₃Ga_5.5Nb_0.5O₁₄ and La₃Ga_5.5Ta_0.5O₁₄ crystals. These crystals hold promise for lasers with self-multiplication of generation frequency. The excitation was achieved at room temperature with diode-laser pumping.
