An optical cavity, resonating cavity or optical resonator is an arrangement of mirrors or other optical elements that forms a cavity resonator for light waves. Optical cavities are a major component of lasers, surrounding the gain medium and providing feedback of the laser light. They are also used in optical parametric oscillators and some interferometers. Light confined in the cavity reflects multiple times, producing modes with certain resonance frequencies. Modes can b… Web#microwaveengineering #cavityresonator #waveguidesRavi Teja Creative Catchers !!Please Like share & Subscribe !!cavity resonatorcavity restorationcavity reso...
