The Dye Laser is a Liquid Laser. Liquid lasers are those lasers which uses liquid as an active medium.
Definition of Microwave
Microwave is a kind of electromagnetic wave. In a broad sense, the microwave frequency range is from 300 MHz to 300 GHz.
Microwave Equipment Category
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. We can design the oscillator with the use of coil and capacitors.
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 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.
The area from the surface the ground towards the sky all over the earth. These different type of gasses are present is called atmosphere.
Three types of rays emits continuously from a radium material. These rays are known as alpha rays (a rays), Beta rays (p rays) and gamma rays (x rays). Gamma rays also know as x-rays.
The frequencies which are beyond the limit of hearing are called ultrasonic. The ultrasonic waves are of frequencies above 20000Hz (20 KHz).
The UJT Stand for Uni Junction Transistor. It has one PN junction and three terminals. As shown in the below figure.
In electronics timers the output of the timing element is used as a trigger pulse for BJT, FET and UJT, the active devices element signal is amplified and this way this signal is used for the load
