Presentation Transcript


  1. Nicholas DiPreta Lasers and Optics

  2. Optics • Science of light • How light behaves and interacts with matter

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

  4. Laser Lab Study Option (1) • Optical Tweezers • momentum of photons in a focused laser beam to exert a force on and ultimately trap microscopic particles • Manipulate microscopic matter • DNA

  5. Optical Vortices (2) • 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.

  6. Variable Lens • Ex: liquid lens • Could help to enable ground based telescopes to view more accurate images • Variable lenses affect the wave front aberrations
