Nonlinear Optical Absorption of Glassy Thin Films Containing InSb Nanocrystals

  • Nonlinear optical absorption of glassy thin films containing InSb nanocrystals was measured by Z-scan technique using Gaussian beam of He-Ne laser (632.8 nm). Both two-photon and saturation absorptions were observed in the composite thin films containing InSb nanocrystals with different average sizes. An enhanced nonlinear optical coefficient was achieved.
