- An attempt at using laser ablation of biofabricated coralline skeletal material Porites lutea for particle deposition is described. The deposition was performed in an evacuated chamber by pulses of the second harmonic (532 nm) of a Nd:YAG laser. The morphology and the local structure of the deposited films were characterized by scanning electron microscopy, X-ray diffraction, confocal Raman microscopy, and transmission electron microscopy. The as-deposited coatings partially retained the inorganic constituent of the CaCO 3 CaCO target and mostly transformed to CaO. The crystalline phase was changed from solely aragonite in the target to a mixture of aragonite and calcite microparticles and CaO nanofeatures.
