Presentation transcript:

Nicholas DiPreta

 Science of light  How light behaves and interacts with matter

 Light Amplification by Stimulated Emission of Radiation  Cavity, with plane or spherical mirrors at the ends, that is filled with lasable material

 Optical Tweezers  momentum of photons in a focused laser beam to exert a force on and ultimately trap microscopic particles  Manipulate microscopic matter  DNA

 beams of light with helical wave fronts that resemble a corkscrew  used in optical tweezers –torque  quantum computing - ability to represent more than two logical states.

 Ex: liquid lens  Could help to enable ground based telescopes to view more accurate images  Variable lenses affect the wave front aberrations
