Laser Guidance Apparatus

The Laser Guidance Apparatus is for guiding/writing nano particles. Particles to be guided are suspended in water and nebulized. The mist from the nebulizer caries the particles aloft and into the path of the laser beam. The gradient optical force of the laser beam draws the particles into the fiber. The CCD camera and VCR are used to monitor the trajectory of the particles (scattered light) through the fiber to measure particle velocity.

The animation is based on the instrumentation employed by Dr. Frank Underdown, nanotechnology entrepreneur and founder of the Keweenaw Nanoscience Center.
