Precision measurement of the stimulated emission wavelength and continuous tuning of YAIO3:Nd3+ laser radiation due to 4F3/2→ 4I13/2 transition

Nonlinear optics methods were used in a precision measurement of the wavelengths of stimulated radiation (1339.3 and 1341.3 nm) emitted from Nd³⁺ ions in a YAIO₃ crystal at 300°K as a result of the auxiliary transition ⁴F_3/2→ ⁴I_13/2. Continuous tuning of the frequency within the luminescence profiles of the investigated lines was achieved under various conditions. The results obtained were used also to refine the crystal-splitting scheme of the ⁴I_13/2 multiplet of the Nd³⁺ ions in YAIO₃.
