What type of pulse widths are considered more aggressive and lead to quicker heating and cooling?

Short pulse widths are considered more aggressive in the context of laser treatments because they deliver energy in a concentrated manner over a brief period. This rapid delivery of energy leads to quicker heating of the target tissue, which can enhance the effectiveness of the treatment while minimizing the risk of surrounding tissue damage. The fast heating creates a thermal effect that can lead to efficient destruction of hair follicles or targeted tissues, depending on the application.

Additionally, the quick cooling associated with short pulse widths helps to protect the surrounding skin from overheating, allowing for a clear focus on the area being treated without excessive collateral damage. This makes short pulse widths particularly beneficial in procedures requiring precision and rapid thermal effects. In contrast, longer pulse widths may heat the tissue more gradually, which may not achieve the same quick therapeutic effects as short pulses.
