Summary:PROBLEM TO BE SOLVED: To overcome the many of limitations of the prior art by increasing control over selected characteristics of fractional treatment zones.SOLUTION: A fractional treatment system may be configured with a laser wavelength that is selected such that absorption of the laser wavelength within the tissue increases as the tissue is heated by the laser (e.g., 1,390-1,425 nm). Desirably, the laser wavelength is primarily absorbed within a treated region of skin by water and has a thermally adjusted absorption coefficient within the range of about 8 cm-1 to about 30 cm-1. An adjustable mechanism may be used to adjust the beam shape, beam numerical aperture, beam focus depth, and/or beam size to affect the treatment depth and or the character of the resulting lesions. The system may be designed to be switchable between a treatment mode that is semi-ablative and a treatment mode that is not semi-ablative.
