A nonlinear change in the absorption at discrete frequencies has been observed in chrysotile asbestos samples whose hollow channels, ^6 nm in diameter, were filled with GaAs. The effect is attributed to saturation of optical transitions between quantum-well levels in GaAs quantum wires as they are excited by picosecond laser pulses. © 1995
