Which term refers to the vapor and particulates emitted during laser operation?

• A. Fluence
• B. Plume
• C. Pump
• D. Modalities

Answer: (B)

When a laser interacts with tissue, it can vaporize tiny amounts of material and eject fine particles into the air. This combination of vapor and airborne particulates is called plume. It’s the specific term for the emissions produced during laser operation, distinguishing it from other laser-related concepts. For example, fluence is the amount of energy delivered per unit area, which describes how much energy reaches the target but not what comes off the tissue. The pump refers to the energy source that powers the laser, not what is emitted. Modalities describe different treatment approaches or types of laser therapy, not the emissions themselves. Understanding plume matters because it can carry biological material, so proper safety measures—such as smoke evacuation, appropriate eye and respiratory protection, and good room ventilation—are used to minimize exposure.
