In what scenarios is a low-power laser typically utilized?

Low-power lasers are primarily utilized in therapeutic applications, such as pain management and wound healing, because they can deliver specific wavelengths of light that promote biological effects without causing significant damage to surrounding tissues. These lasers operate at lower energy levels which are ideal for stimulating cellular processes, enhancing blood circulation, and reducing inflammation or pain in conditions like arthritis or soft tissue injuries.

The mechanisms by which low-power lasers aid in healing involve photobiomodulation, where light absorption by the cells triggers various biochemical pathways that support repair and regeneration. This application is distinctly different from high-powered lasers used in industrial settings, which involve significant heat and energy to cut or weld materials, or in contexts like explosive device initiation where precision and high energy are necessary. Similarly, large-scale construction projects typically require much more powerful light sources for visibility, making low-powered lasers unsuitable for those applications.
