Which component delivers laser energy through fiber optics to the treatment area?

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

Answer: (D)

The delivery system is the component that transmits laser energy to the treatment area through fiber optics. It includes the fiber optic cable and handpiece that carry and focus the laser energy from the source to the skin, delivering the correct spot size and energy density to the target tissue. The other terms describe different roles: the interpulse delay is the pause between laser pulses and influences timing and tissue response, the optical cavity is the laser’s internal resonator where light is generated, and the chromophore is the tissue pigment that absorbs the laser energy. The delivery system is the conduit that actually brings that energy to the treatment site via fiber optics.
