  • LIGO (Laser Interferometer Gravitational-Wave Observatory)

    Introduction The Laser Interferometer Gravitational-Wave Observatory (LIGO) represents one of the most ambitious and successful projects in experimental physics. It was designed to detect gravitational waves, ripples in the fabric of spacetime caused by violent cosmic events like the collision of black holes or neutron stars. Theoretical Background: Gravitational Waves Gravitational waves, predicted by Einstein’s…

  • Maser

    Introduction A maser is a device that produces coherent electromagnetic waves through amplification by stimulated emission. The term “maser” is an acronym for “Microwave Amplification by Stimulated Emission of Radiation”. Masers are the microwave-frequency precursor to the better-known laser (Light Amplification by Stimulated Emission of Radiation). Basic Working Principle The basic principle of a maser…
