• The nonlinear refractive index (n 2 ) of several NaT(WO 4 ) 2 (T = Y, La, Gd, Lu and Bi) and NaY(MoO 4 ) 2 femtosecond laser crystals has been measured using the z-scan technique. These tetragonal crystals with structural local disorder present significant n 2 values, which should allow their efficient laser pulsed operation by Kerr-lens mode locking, especially NaBi(WO 4 ) 2 , 68×10 -16  cm 2 /W (for σ light), which is about twice than for the others. This difference is attributed to the high polarizability associated with the lone electron pair of Bi 3+ .
