Abstract
Morphological characterization and the nonlinear optical properties of laser ablated germanium nanoclusters are discussed in this paper. Laser ablated films contain micron sized droplets that are composed of nanoclusters. The clusters have cubic and tetragonal symmetry. Results from TEM, AFM, and XRD are presented for the surface characterization. Nonlinear absorption is observed at very low light intensities and nonlinear absorption and refraction are seen at peak light intensities of 18 KW/cm2 at γ = 532 nm. The estimated change in refractive index is 0.05 at these intensity levels.
