ABSTRACT:
A method and a system are provided for protecting patients and equipment from the damaging effects of stray laser light emissions. Porous barrier materials are selected to have a pore geometry functionally related to the wavelength of emitted laser so as to cause destructive interference of the light beam when the beam encounters the porous material.
