Photobiomodulation refers to the way in which light energy is absorbed by cells, leading to various beneficial cellular effects. This process typically involves low-level laser therapy or light-emitting diodes (LEDs) that emit specific wavelengths of light. When these light wavelengths penetrate the tissue, they can interact with chromophores within the cells, which may result in increased mitochondrial activity, enhanced ATP production, and promotion of healing and regeneration.

This understanding is critical because photobiomodulation is used for therapeutic purposes in a broad range of applications, including pain relief, inflammation reduction, and tissue repair, making it a vital concept in fields like medicine and rehabilitation. The process emphasizes the biological impact that light can have on cellular functions, which distinguishes it from other terms related to lasers, such as those concerning laser manufacturing or tissue removal techniques.
