The word LASER stands for light amplification by stimulated emission of radiation.

The inverse square law is common law of physics related to light discussion. The inverse square law states that

There are following methods of cavity resonator excitation. Loop Excitation, Probe Excitation, Aperture Excitation

The Dye Laser is a Liquid Laser. Liquid lasers are those lasers which uses liquid as an active medium.

Microwave is a kind of electromagnetic wave. In a broad sense, the microwave frequency range is from 300 MHz to 300 GHz.

Digital Microwave Communication Equipment explanation in detail with help of diagrams and images.

The CO2 stands for carbon dioxide. In CO2 laser the laser light takes place within the molecules of carbon dioxide rather than within the atoms of a pure gas.

At the lower mode of frequencies the oscillation and amplification is carried out by conventional wires and transistors networks.

The backward wave oscillator is made of tube in which heater, cathode, helix, feedback conductor and focusing electrodes and anode is located.

Argon is the name of gas. The argon laser active medium consists of this gas, where the lasing takes place due to ions of argon gas.
