What is the consequence of having too short of a pulse width during a laser treatment?

Having too short of a pulse width during laser treatment can lead to the burning of the skin. When a laser emits energy in very short bursts, the energy can be delivered too quickly for the skin to absorb it safely. This rapid energy transfer may cause excessive heat build-up in the upper layers of the skin, leading to thermal damage. The skin’s ability to dissipate heat is compromised, which increases the risk of burns and injury.

In contrast, a longer pulse width allows for better absorption of the energy by the target tissue while minimizing damage to surrounding skin. Properly timed and controlled pulse widths are essential for achieving therapeutic effects such as hair removal, skin rejuvenation, and cooling without causing harm to the skin.
