    摘要： Embodiments of the present invention generally describe systems, devices, and methods for directly measuring pulse profiles during pulse delivery. In some embodiment, the pulse profiles may be measured while the pulse is delivered to ablate a material. Embodiments, may calculate ablation spot parameters based on the pulse profiles and may refine one or more subsequent laser pulses based on deviations from the calculated ablation spot parameters from desired ablation spot parameters. In some embodiments, a fluence profiler is provided. The fluence profiler may measure a pulse profile of a laser pulse from a portion of the laser pulse. The fluence profiler may utilize a UV radiation energy sensor device and a camera-based imager. The measurements from the UV radiation energy sensor device and the camera-based imager may be combined and scaled to provide a measured pulse profile that corresponds to the delivered pulse.

    摘要： A method for treating a condition in a tissue, includes the steps: (1) providing a PS within the tissue; (2) irradiating the tissue containing the PS with a first light of a first wavelength; and (3) irradiating the tissue containing the PS with a second light of a second wavelength so as to treat the condition in the tissue, wherein: (a) the PS absorbs light at the first wavelength and the second wavelength; and (b) the second light is more strongly absorbed by the tissue than the first light or vice versa, so as to achieve a predetermined absorbed photon density gradient. An apparatus for conducting the method includes first and second light sources, a power supply, a focusing device, and a controller which adjusts light emission such that I(d)=I(λ1 at d=0)×exp (μeff (λ1)×d)+I(λ2 at d=0)×exp (μeff(λ2)χd).

    摘要： An increasing number of non-invasive skin treatment devices are being provided for use by consumers instead of by medical professionals. Such home use raises new concerns, such as safety and treatment efficacy. The invention improves on existing devices and treatment methods. The invention provides a device and method, wherein a light source is configured and arranged to provide a first (31) and a second (32) region of non-zero intensity within a transverse cross-section of a laser light beam (21) having a single higher-order laser beam mode, and a third region (33), disposed between the first (31) and second (32) regions, of lower light intensity than the non-zero light intensity. The first (31) and second (32) regions are configured to create, during use, a lesion in skin tissue in the focal spot of the laser light beam, and the third (33) region is configured to avoid creating in the focal spot, during use, a lesion in skin tissue between the lesions created by the first and second regions. For example, the light source may be configured and arranged to produce laser light in a higher mode, the order being higher than fundamental mode. The intensity pattern of the beam profile, with its regions of substantially differing intensity, is substantially constant along the propagation axis. This provides an area in the skin tissue in the focal spot at the treatment location with substantially no lesions, disposed between areas of lesions.

    摘要： A light based skin treatment device (10, 20) is provided, comprising a light source (18) for providing an incident light beam (21) for treating a skin (30) by laser induced optical breakdown (LIOB) of hair or skin tissue, a transparent exit window (14) for allowing the incident light beam (21) to exit the device (10, 20), and an optical system for focusing the incident light beam (21) into a focal spot (221, 222) in the hair or skin tissue outside the skin treatment device (10, 20). The exit window (14) comprises an outer surface (41, 42, 43, 44) having optical scattering properties such that, for a predetermined power and pulse duration of the incident light beam (21), when the outer surface (41, 42, 43, 44) is in contact with a medium having a refractive index equal to a refractive index (n1) of the exit window (14), a dimension of the focal spot is sufficiently small for a power density of the incident light beam (21) in the focal spot to exceed a threshold value for inducing a LIOB phenomenon in the focal spot, and when the outer surface (41, 42, 43, 44) is in contact with a medium having a refractive index equal to a refractive index (n2) of air, a dimension of the focal spot is sufficiently large for a power density of the incident light beam (21) in the focal spot not to exceed the threshold value for inducing a LIOB phenomenon in the focal spot.
