There are two groups of microwave devices. Semiconductor Devices, Tube Devices

Microwave refer to high frequencies (above 300MHz) and short wave lengths, at the microwave components depends on the changing

The Traveling-wave tube can be used as a medium or high power microwave, amplifier. The TWT, because of its construction and working

A maser is a device that produces coherent electromagnetic waves through amplification by stimulated emission.

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.

The lasers having gas as an active medium is called gas lasers. Generally there are three classes of gas lasers.

Detectors are device used with lasers to detect or discover the presence of something. There are two categories of the detectors

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.
