1. An apparatus for performing a dermatologic treatment on a target area of skin, comprising:
- a source for generating optical electromagnetic radiation (EMR) having at least one wavelength being absorbable by a chromophore in the skin, an applicator optically coupled to the source for applying the EMR to the target area, and controls to cause the source to generate EMR having a duration in a range of about several seconds to about 20 seconds.

Abstract
A method and apparatus are provided for performing a medical procedure on a patient, for example a dermatological procedure, by use of electromagnetic radiation (EMR) having a relatively low peak power, and in particular a peak power low enough so as not to result in a phase change in the heater or chromophore absorbing radiation which would result in a significant reduction in its absorption, and of relatively long duration which is generally greater than, sometimes significantly greater than, the thermal relaxation time of the irradiated target.
