Increasing your spot size keeps photons in which area?

Increasing the spot size in laser hair removal treatments directly affects the beam path of the laser. When the spot size is larger, it allows for a broader area to be covered with the emitted light energy, which in turn ensures that more photons are concentrated in that larger beam path. This results in an increased effective treatment area, as the laser energy can reach more hair follicles during a session.

In laser hair removal, the design of the beam path is crucial for ensuring that the energy delivered is consistent and uniform across the surface being treated. A larger spot size minimizes the number of passes needed over the same area, making the treatment process more efficient and potentially reducing discomfort for the patient. This is particularly important in larger treatment areas, where a smaller spot size would require multiple passes, increasing the time required and possibly leading to uneven energy distribution. Hence, focusing on the beam path is vital for achieving the desired therapeutic effect safely and effectively.
