CO2 Laser (The molecular gas laser)
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.
Cavity Resonator
At the lower mode of frequencies the oscillation and amplification is carried out by conventional wires and transistors networks.
Backward Wave Oscillator & Circulator
As shown in the given diagram, the backward wave oscillator is made of tube in which heater, cathode, helix, feedback conductor and focusing electrodes and anode is located.
Argon LASER (An Ion Gas Laser)
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.
