Energy Conservation

Definition

Energy conservation refers to the principle that energy cannot be created or destroyed but can only change forms. This concept is crucial in understanding how energy interacts within systems, especially when dealing with phenomena like nonlinear optical effects where energy transfer and transformation occur. It emphasizes the importance of efficient energy use and the need for sustainable practices in the manipulation and application of optical technologies.
