ABSTRACT:
Method and active media for controlled production of physical and refractive index inhomogeneities in a volume of a suspension medium by use of at least two intersecting beams of electromagnetic radiation matched to the excited state properties of molecules in the media. In addition, complex three-dimensional physical and chemical structures are produced by selective excitation of different types of molecules in the media and by employing transportive capabilities of liquid or gaseous support medium.
