摘要：

Nonlinear absorption in copper-doped silicate glasses was investigated by the Z-scan technique using second harmonic radiation of a Nd:YAG laser (lambda = 532 nm, tau = 55 ps). The simultaneous influence of saturated and reverse saturated nonlinear absorption processes was analyzed. The nonlinear absorption coefficient and the saturation intensity of copper-doped glasses at laser intensity of 5.4 x 10(9) W cm(-2) were measured to be 6 x 10(-6) cm W-1 and 4.3 x 10(8) W cm(-2), respectively.
