   Ashkin was able to trap larger particles (10 to 10,000 nanometers in diameter) but it fell to Chu to extend these techniques to the trapping of neutral atoms (0.1 nanometers in diameter) using resonant laser light and a magnetic gradient trap (cf. Magneto-optical trap).

3. Laser projector - Wikipedia

   en.wikipedia.org/wiki/Laser_projector

   A laser projector is a device that projects changing laser beams on a screen to create a moving image for entertainment or professional use. [1] It consists of a housing that contains lasers, mirrors , galvanometer scanners, and other optical components.

4. Waveguide (optics) - Wikipedia

   en.wikipedia.org/wiki/Waveguide_(optics)

   This mechanism can be used to trap light in a waveguide. d. This is the basic principle behind fiber optics in which light is guided along a high index glass core in a lower index glass cladding. The basic principles behind optical waveguides can be described using the concepts of geometrical or ray optics, as illustrated in the diagram.

5. Magneto-optical trap - Wikipedia

   en.wikipedia.org/wiki/Magneto-optical_trap

   By detuning a laser beam to a frequency less than the resonant frequency (also known as red detuning), laser light is only absorbed if the light is frequency up-shifted by the Doppler effect, which occurs whenever the atom is moving towards the laser source. This applies a friction force to the atom whenever it moves towards a laser source.

6. Laser pointer - Wikipedia

   en.wikipedia.org/wiki/Laser_pointer

   Red (635 nm), blueish violet (445 nm), and green (520 nm) laser pointers. A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.

   The most one can say in “Mouse Trap’s” favor is that its rote professionalism at least makes for less painful a slog than “Blood and Honey.” The big disappointment with films of this ilk ...
