What is the frequency of gamma rays in GHz?

Gamma rays are the highest energy EM radiation and typically have energies greater than 100 keV, frequencies greater than 10 19 Hz , and wavelengths less than 10 picometers.

Broadband terahertz pulses can be generated by exciting THz-PCAs with a femto-second short pulse laser . Using a femto-second laser with ~ 100 fs optical pulse duration, terahertz pulses with their frequency content extended up to around 5 THz and an average power of a few μW can be achieved.

Terahertz (THz) is a unit of measure of frequency that is equal to 1 trillion hertz (1012 Hz) . It usually refers to the frequency of an electromagnetic wave, which is a part of the electromagnetic spectrum invisible to the naked eye that lies in between the microwave and the infrared range.

Between microwaves & infrared The terahertz range refers to electromagnetic waves with frequencies between 100 GHz and 10 THz, or wavelengths between 3 mm and 30 μm . Light between radio waves and infrared has some unique properties. Terahertz can “look inside” plastics and textiles, paper and cardboard.
