Abstract
Subject headings
Close
- The nonlinear refractive index (n(2)) of several NaT(WO4)(2) (T = Y, La, Gd, Lu and Bi) and NaY(MoO4)(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(WO4)(2), 68x10(-16) cm(2)/W (for sigma light), which is about twice than for the others. This difference is attributed to the high polarizability associated with the lone electron pair of Bi3+.
