Can you make a radio wave laser?

A normal laser has a frequency that depends on the transition energy for electrons from one state to another in the gain medium. These energies are much higher than those of individual radio waves, so a classic laser that generates radio waves is not possible.

What is the maximum range of radio waves?

Radio waves have the longest wavelengths in the EM spectrum, according to NASA, ranging from about 0.04 inches (1 millimeter) to more than 62 miles (100 kilometers)….Bands of radio waves.

Band	Frequency range	Wavelength range
Medium Frequency (MF)	300 kHz to 3 MHz	100 m to 1 km
High Frequency (HF)	3 to 30 MHz	10 to 100 m

How masers are different from lasers?

The difference between a laser and a maser is that the photon from a laser comes in the form of visible light , while a photon from a maser comes in the form of a microwave . M.A.S.E.R. Stands for Microwave Amplification by Stimulated Emission of Radiation.

Which material is used for maser?

The name is an acronym derived from “microwave (or molecular) amplification by stimulated emission of radiation.” The first maser used a beam of ammonia molecules that passed along the axis of a cylindrical cage of metal rods, with alternate rods having positive and negative electric charge.

How do lasers and masers work?

We learned how lasers emit photons in the infrared to ultraviolet range when their electrons are excited to a higher energy state and then drop back down to their original state, while masers emit photons in the microwave range when their electrons fall down to a lower energy state.

Is it possible to generate radio waves with a laser?

These energies are much higher than those of individual radio waves, so a classic laser that generates radio waves is not possible. However, if you look at more exotic devices like the free electron laser (FEL), then what you describe is possible.

What is the frequency range of radio waves?

Frequency Range of Radio Waves Band Frequency of Radio Waves Radio Waves Wavelength ELF (Extremely Low Frequency) <3kHz >100 km VLF (Very Low Frequency) 3 to 30 kHz 10 to 100 km LF (Low Frequency) 30 to 300 kHz 1m to 10 km MF (Medium Frequency) 300 kHz to 3 MHz 100 m to 1 km

Is radar a radio wave laser?

I believe that, since the waves are all in phase, RADAR qualifies as a “radio wave laser” except for the “stimulated emission of radiation” part, which I’m not sure about. (I don’t think there are lots of metastable excited states of a RADAR array de-exciting resonantly, but there might even be a way of looking at it that way.)

How do radio waves travel at the speed of light?

At 300 GHz, the frequency of radio waves is 1 mm, and at 3 kHz is 100 km. They travel at the speed of light simply like all other electromagnetic speeds of radio waves do. Astronomical objects make all the waves that have normally happened.
