摘要：

Nonlinear optical absorption at discrete frequencies (bleaching bands) has been observed for GaAs quantum wires in chrysotile asbestos nanotubes with average diameter approximate to 6 nm. The induced decrease of absorption has been explained by filling of the size-quantized energy levels of quantum wires with nonequilibrium carriers (saturation effect). Strong (chi((3))= 10(-8) e.s.u.) and fast (relaxation time less than or equal to 50 ps) third order optical nonlinearity has been determined.
