What is the length of time that energy is applied with the laser called?

The length of time that energy is applied with the laser is referred to as pulse duration. This term specifically describes the duration of a single pulse of laser energy delivered during treatments, which is crucial for determining the effectiveness and safety of laser procedures.

In laser applications, the pulse duration can influence the thermal effect on the target tissue, as well as the surrounding skin. Different procedures may require varying pulse durations to achieve the desired effect, whether for hair removal, skin rejuvenation, or tattoo removal. Understanding pulse duration allows practitioners to optimize treatment settings based on individual client needs and skin types, enhancing outcomes and minimizing potential adverse effects.

Other terms in the options, while they might seem similar, do not accurately describe this concept. Pulsation time might imply a rhythmic pattern or a cycle rather than specific duration of energy application, energy duration is vague and does not specify that it refers to a pulse, and application interval suggests a time between pulses rather than the duration of the pulse itself. Thus, pulse duration is the most precise and relevant term in this context.
