摘要：
1. A light-based skin care device (10, 20), comprising: a light source (18) for providing an incident pulsed light beam (21) for skin care (30) by means of laser-induced optical breakdown (LIOP) of hair or tissue skin, a transparent exit window (14) to allow the incident light beam (21) to exit the device (10, 20), and an optical system for focusing the incident light beam (21) into the focal spot (221, 222) in the hair or skin tissue outside skin care devices (10, 20), wherein the exit window (14) comprises an outer surface (41, 42, 43, 44) having such optical scattering properties 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 refractive index equal to the refractive index (n1) of the exit window (14), the size of the focal spot (222) is small enough so that the power density of the incident light beam (21) in the focal spot (222) exceeds the threshold value for inducing the LIOP phenomenon in the focal spot (222), when the outer the surface (41, 42, 43, 44) is in contact with a medium having a refractive index equal to the refractive index (n2) of air, the size of the focal spot (221) is large enough so that the power density of the incident light beam (21) in the focal spot (221) did not exceed the threshold value for inducing the LIOP phenomenon in the focal spot (221) .2. A light-based skin care device (10, 20) according to claim 1, wherein the outer surface (41, 42, 43, 44) has a surface roughness with a rms value (RMS) given by the ratio (n1-n2) · RMS>； C · λ, where (n1-n2) is the difference between the refractive index (n1) of the exit window (14) and the refractive index (n2) of air, C is1. Устройство (10, 20) ухода за кожей на основе света, содержащее:источник (18) света для обеспечения падающего импульсного пучка (21) света для ухода за кожей (30) посредством лазерно-индуцированного оптического пробоя (ЛИОП) волос или ткани кожи,прозрачное ок
