Patent Images
1. A light energy treatment head comprising:
- at least one optical energy emitting element mounted within the head and oriented to direct optical energy to a target region of skin;
a transparent element disposed between the energy emitter and the target region of skin during use, the transparent element having good thermal transfer properties; and
at least one cooling mechanism for extracting heat from both the emitter and the transparent element.

Abstract
A light energy delivery head is provided which, in one aspect, mounts laser diode bars or other light energy emitters in a heat sink block which is adapted to cool both the emitters and a surface of a medium with which the head is in contact and to which it is applying light energy. In another aspect, various retroreflection configurations are provided which optimize retroreflection of back-scattered light energy from the medium. The size of the aperture through which light energy is applied to the medium is also controlled so as to provide a desired amplification coefficient as a result of retroreflection.
