The rate or amount of energy delivered to a specific area in laser applications is termed?

Fluence refers to the total energy delivered per unit area during a laser procedure. It is a crucial concept in laser applications, as it helps determine the effectiveness of the treatment based on how much energy is being applied to the target tissue. The measurement of fluence is typically expressed in joules per square centimeter (J/cm²). Understanding fluence is essential for practitioners to ensure that the laser energy applied is appropriate for the desired therapeutic effect without causing damage to surrounding tissues. Factors such as the type of tissue, the specific laser wavelength, and the treatment goals must all be considered in relation to fluence to achieve optimal results. In contrast, other terms like intensity rely more on power distribution over time rather than specifically measuring total energy per area.
