What causes laser plume?

The phenomenon of laser plume is primarily caused by the interaction of the laser beam with tissue. When a laser is applied to the skin or other biological materials, it generates energy that can lead to various thermal and photochemical effects. As the laser energy penetrates the tissue, it causes cellular material to vaporize and produce smoke or plume, commonly referred to as laser plume. This plume can contain various byproducts, including vaporized tissue, blood, and cellular debris.

Understanding this process is crucial for practitioners, as laser plume may carry pathogens and pose potential health risks; therefore, proper safety protocols, such as the use of smoke evacuation systems, are essential.

The other options focus on different aspects of laser usage or equipment, but they do not accurately define the process that specifically produces laser plume.
