    摘要: The invention features a probe for selectively delivering laser radiation to a first tissue having a first index of refraction relative to a second tissue having a second index of refraction less than the first index. The probe includes a laser transmitting medium having an optical axis and a tissue-contacting surface. In some embodiments, the optical axis contacts the tissue-contacting surface at an angle that is less than the critical angle for an interface between the tissue-contacting surface and the first tissue and greater than or equal to the critical angle for an interface between the tissue-contacting surface and the second tissue, wherein during operation the probe directs the laser radiation along the optical axis to the tissue-contacting surface. In other embodiments, the optical axis forms an angle with the tissue-contacting surface, and during operation the probe directs the laser radiation along the optical axis to the tissue-contacting surface, transmits a first amount of laser energy through the tissue-contacting surface when contacting the first tissue, and transmits a second amount of laser energy through the tissue-contacting surface when contacting the second tissue, wherein the angle is selected such that the first amount of laser energy is at least twice the second amount of laser energy. The invention also features related methods for selectively delivering laser radiation to tissue based on refractive index.

    摘要: A confocal microscope for generating an image of a sample includes a first scanning element for scanning a light beam along a first axis, and a second scanning element for scanning the light beam at a predetermined amplitude along a second axis perpendicular to the first axis. A third scanning element scans the light beam at a predetermined amplitude along a third axis perpendicular to an imaging plane defined by the first and second axes. The second and third scanning element are synchronized to scan at the same frequency. The second and third predetermined amplitudes are percentages of their maximum amplitudes. A selector determines the second and third predetermined amplitudes such that the sum of the percentages is equal to one-hundred percent.

    摘要: A method and apparatus for simultaneously effecting the removal of multiple hairs from a skin region by using light energy to destroy hair follicles in the region. Light energy is applied to the region through an applicator which converges the light energy to enhance destruction of desired portions of the follicles, is preferably pressed against the skin region to deform the upper layers of the skin reducing the distance from the skin surface to portions of hair follicles which are to be destroyed, including the bulge and papilla of the follicles, and which applicator is preferably cooled to minimize or eliminate thermal damage to the epidermis in the region being irradiated. Parameters for the irradiation, including pulse duration, are selected to effect complete damage of desired portions of the hair follicles in the region with minimal damage to surrounding tissue and to the patient's epidermis.
