Understanding Energy Density
Energy density is one of the most important parameters in laser surgery. Understanding how the laser energy is "spatially" delivered is key. One Watt of energy delivered over a square-foot is insignificant to tissue. However, one Watt of energy delivered in spot the size of a pin-head will drill a hole in tissue. For fiber-delivery lasers such as the Odyssey, the relevant spatial parameters are the fiber core diameter and the distance from the operating plane. The fluence, calculated by this formula, determines the magnitude of the laser interaction.
