    • In a fractional treatment system, an adjustable mechanism can 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. Adjustment of these parameters can improve the efficiency and efficacy of treatment. Illustrative examples of adjustable mechanisms include a set of spacers of different lengths, a rotatable turret with lens elements of different focal distances, an optical zoom lens, and a mechanical adjustment apparatus for adjusting the spacing between two optical lens elements. In one aspect, the fractional treatment is configured with a laser wavelength that is selected such that absorption of the laser wavelength within the tissue decreases as the tissue is heated by the laser (e.g., 1480-1640 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 7 cm−1 to about 26 cm−1.
    • 在分数处理系统中,可以使用可调节的机构来调整光束形状,光束数值孔径,光束聚焦深度和/或光束尺寸,以影响治疗深度或所得损伤的特征。 这些参数的调整可以提高治疗的效率和疗效。 可调节机构的说明性实例包括一组不同长度的间隔物,具有不同焦距的透镜元件的可旋转转台,光学变焦透镜和用于调节两个光学透镜元件之间的间距的机械调节装置。 在一个方面,分数处理配置有激光波长,激光波长被选择为使得组织内的激光波长的吸收随着组织被激光加热而减小(例如,1480-1640nm)。 期望地,激光波长主要被水吸收在皮肤的处理区域内,并且具有在约7cm -1至约26cm -1的范围内的热调节吸收系数, SUP>。
