Lasers and IPL are classified as which type of devices?

• A. Radiation producing devices
• B. Radiation emitting devices
• C. Optical devices
• D. Thermal devices

Answer: (B)

Lasers and IPL deliver energy to tissue in the form of light, i.e., radiant energy. The key idea is that their defining function is emitting electromagnetic radiation to achieve their cosmetic effects. That’s why they’re classified as radiation emitting devices. They aren’t simply labeled as optical devices, since the important trait is the emission of energy as radiation rather than just handling light. They aren’t primarily thermal devices, even though heat is a consequence of how they act on tissue, because the core classification rests on emitting radiation.
