:Light Amplification by Stimulated Emission of Radiation

A device produces a coherent beam of optical radiation by stimulating electronic, ionic, or molecular transitions to higher energy levels
When they return to lower energy levels by stimulated emission, they emit energy.


PROPERTIES

Monochromatic
Concentrate in a narrow range of wavelengths (one specific colour).

Coherent
All the emitte ....etc

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted through space rather than being guided through an optical cable. These beams of li ....etc

The Robot control using the wireless communication and the serial communication



Executive Summary
The NASA Robotics Alliance Cadets Program is being designed to be implemented at a
very low start-up cost, and to make this goal obtainable, the program is being developed
using low to no cost components from already developed, well-tested and robust
engineering testbeds.
In this project we are trying to establish both wireless communication between the mobile
Robot and the rem ....etc

About Nanotechnology

Nanotechnology draws its name from the prefix nano. A nanometer is one-billionth of a meter a distance equal to two to twenty atoms (depending on what type of atom) laid down next to each other. Nanotechnology refers to manipulating the structure of matter on a length scale of some small number of nanometers, interpreted by different people at different times as meaning anything from 0.1 nm (controlling the arrangement of individual atoms) to 100 nm or more (anything smaller than microtechnology). Richard Feynman was ....etc
