Light is commonly associated with the production of heat, which can denature, coagulate or vaporise tissues depending on the energy output and the exposure time. Specific interactions causing a localised heating and tissue ablation require short pulses, and laser outputs can range from femtoseconds to continuous wave operation. The low divergence of light allows for non-contact methods of treatment and reduces the risk of infection.
Light emitted from lasers is usually plane polarised, and this property may be of use in modifying cell behaviour. Unable to display preview. Download preview PDF. Skip to main content.

Photophysical processes in recent medical laser developments: a review. If you are considering having a tattoo removed , it can be helpful to learn some of the history and basics about tattoo removal. Unlike the sometimes impulsive decision, followed by a few hour procedure or less process of getting a tattoo, removing a tattoo requires a commitment to time and often multiple visits.
From the length of time you will need to wait between treatments, you should learn about which type of tattoos are the easiest to remove, and even a discussion about how painful these procedures may be. The most common "complication" of selective photothermolysis is the inability to resolve the pigmented skin lesion completely. The procedure works best when there is a significant contrast between the color of the skin and the normal surrounding skin.
The procedure is also limited to what can be accomplished by the laser surgery. For example, selective photothermolysis may resolve some skin changes secondary to aging or treat some problems related to inflammatory acne, but certainly not all. As with any laser technique, there can be damage burns to surrounding normal tissues in some cases.
Procedures such as selective photothermolysis provide another method for people to treat skin conditions ranging from unwanted tattoos to congenital port wine stains, to changes related to inflammatory acne. It's likely that with current knowledge, procedures such as this will continue to improve in ways that help physicians treat unwanted skin coloring without harming nearby tissues.
