Picosecond pumping resulted in efficient stimulated Raman scattering in the NaLa(MoO4)2 with two Raman-active vibrational modes νR = 320 and 888 cm-1. All Stokes and anti-Stokes Raman components were identified for different orientations of the crystal and different polarisations of the excitation. For the first time, infrared pump radiation (λp = 1.06415 μm) was converted to the visible range (λas81 = 0.6058 μm) in a Raman-active insulator crystal (νR1 = 888 cm-1).
