Electromagnetic Waves
When the alternating current passes through a wire than it sets up an electromagnetic field that propagate away from the wire.
Q factor (for unloaded cavity resonator)
The Q factor of the cavity resonator is the ratio between the stored energy of the cavity to the power losses in the cavity.
Properties of laser light
We know that laser generates light that has all the characteristics of ordinary light, However there are three important distinct characteristics of laser light that make it different from other ordinary light. These characteristics are Monochromaticity Divergence Coherence Monochromaticity The…

Travelling Wave Maser
Construction The travelling wave MASER (T.W.M) consists of a wave guide structure in which the wire figure or comb is designed. The wire figure is a number of conducting plates situated inside the wave guide once having windows in the…
Maser
A maser is a device that produces coherent electromagnetic waves through amplification by stimulated emission.
Magnetron
The Magnetron is a high power microwave oscillator, uses the interaction of electric and magnetic fields in a cavity to produce oscillations of very high power.
Black Body Radiation for LASER
We know that a body which absorbs all kind of radiation falling on it is called black body. Consider a solid that has a hollow cavity within it. It has a small hole and the radiation can escape only through…
Characteristics of GAS Lasers
The lasers having gas as an active medium is called gas lasers. Generally there are three classes of gas lasers.
Laser Accessories Part 4 (Detectors)
Detectors are device used with lasers to detect or discover the presence of something. There are two categories of the detectors
Laser Accessories Part 3 (Q-Switches)
The Q-Switch is a device which is placed inside the laser cavity. Main purpose of the Q-switch is to rapidly change the feedback of a laser cavity from minimum to maximum.
