Fibre Crystal Mid Infrared Lasers
1,998 wordsFibre crystal mid-infrared lasers As we know, a laser is an optical oscillator made out of a gas, liquid or solid with mirrors at both ends (see, e. g. , The Computer Language Company Inc. , 2007 b). To make the laser work, the material is pumped with light or electricity. This pumping has excited the electrons and has caused them to jump to more high orbits. Some electrons do spontaneously drop back to lower energy levels what releases photons (i. e. quantum's of light). The photons do then sti...

2,475 wordsPropagation as defined by Webster Dictionary as the phenomenon of radio frequency energy traveling through the earths atmosphere, as well as through the empty space above the atmosphere. Once radio-frequency energy has been emitted from an antenna it will travel away from the antenna, where it is generated from, at the speed of light. Once it is sent the wave exists and propagates independently of the system that produces it. This means that changes, which occur at the transmitter (antenna), wil...
