Which of the following is NOT a characteristic of surgical lasers?

The option identified as correct, which is photostimulation, is not a characteristic of surgical lasers. Surgical lasers primarily focus on precision and control during tissue removal or incision. Their main characteristics include the ability to seal blood vessels, which helps minimize bleeding during surgical procedures, and the capability to create excess heating for cutting and coagulating tissue.

Photostimulation refers to the therapeutic effect of light on cellular processes, which is more associated with therapeutic or healing lasers, such as those used in low-level laser therapy (LLLT), rather than surgical lasers. Surgical applications primarily deal with cutting or altering tissue rather than stimulating cellular responses, which distinguishes them from therapeutic modalities.
