What did Jan Tuner study in relation to laser therapy?

The study conducted by Jan Tuner specifically focused on the differences between laser and LED devices, making this answer particularly relevant in the context of laser therapy. Tuner's research highlights how these two types of light sources vary in their mechanisms and applications, which is crucial for understanding their effectiveness in therapeutic settings.

Lasers emit light that is coherent, monochromatic, and collimated, allowing for targeted treatment of tissues at specific depths and limits of penetration. In contrast, LED devices produce non-coherent light that is typically broader in wavelength and less focused. This fundamental difference impacts their therapeutic outcomes, making it essential for practitioners to understand when and how to use each type of device effectively in laser therapy. This knowledge is vital for optimizing treatment protocols and enhancing patient care, which is especially relevant for those involved in laser treatments in clinical practice.
