Communication:Cybernation —— Photonics
Lasers are not new,but they are suddenly hot because laser light has some phenomenal properties.First of all, it is incredibly fast: It is moving at a 186,000 miles per second or 300,000 kilometers per second in Canada which is in the metric system and that is an incredibly fast rate of transferring energy.Light is also an anergy.So the second part of light's power, is that there is no fundamental limit in the amount of energy you can compress in a particular unit in space so you can get energies equal to several atomic bombs, if you will, in a laser pulse. So, lasers have incredible speed and incredible energy.
