Abstract
An applicator is configured with an optical window formed from a first and a second lens section. The applicator is configured for modulating the temperature of a working surface while simultaneously exposing the working surface to a radiation source. The first and the second lens sections form boundaries of a medium cavity for channeling a temperature regulating medium which is preferably a cooled liquid medium. The first lens section has an outer lens and an inner lens which are preferably separated by a distance in the range of 0.1 to 1.0 cm and form boundaries of an insulating region. In a preferred method, a temperature regulating medium is circulated through the medium cavity while exposing a target tissue to laser radiation through the optical window. The insulating region helps reduce fogging of the optical window thereby improving visibility through the window and reducing scattering of the laser radiation. Preferably, the insulating region is under vacuum. Alternatively, the insulating region is configured to channel a second temperature regulating medium. The applicator and system of the instant invention are preferably configured for exposing dermis to a pulsed laser so…
