Which component channels laser energy to the treatment site via fiber optics?

• A. Optical Cavity
• B. Interpulse Delay
• C. Delivery System
• D. Chromophore

Answer: (C)

Understanding how laser systems move energy to the target starts with the delivery path. The delivery system is designed to channel laser energy to the treatment site using fiber optics, guiding the light from the source through flexible cables to the handpiece and then to the tissue with the proper focus and spot size. The optical cavity is where the laser light is generated, not where it travels to the target. The interpulse delay refers to the timing between pulses, and the chromophore is the tissue pigment that absorbs the light and converts it to heat. So, the delivery system is the component that actually carries the energy via fiber optics to the treatment site.
