What does the property of fluence in laser treatments refer to?

Fluence in laser treatments is specifically defined as the amount of energy delivered per unit area. This measurement is crucial for understanding how effectively the laser can target tissue, as it dictates the intensity of the treatment and its potential effects on the skin or other surfaces being treated.

In laser therapy, fluence is expressed in joules per square centimeter (J/cm²), and it plays a key role in determining the results of the treatment, such as hair removal or skin resurfacing. Adequate fluence ensures that enough energy penetrates the desired depth of the tissue to achieve the therapeutic effects, whether they involve heating, coagulation, or destruction of target cells.

The other options touch on different aspects of laser treatments but do not accurately define fluence. The duration of the laser pulse refers to how long the laser is activated, which impacts the thermal effect but does not define fluence itself. The wavelength of the laser light refers to the color of the laser and its absorption properties, which influences how light interacts with different tissues but is separate from fluence. Finally, the temperature of the tissue is a result of the absorbed energy but is not what fluence measures. Thus, fluence is a fundamental concept in laser therapy that directly relates
