Patent number: 11642168Abstract: A pulsed laser skin treatment device is for laser induced optical breakdown of hair or skin tissue. The device has a light exit window to be placed against a surface to be treated such as skin during use. A feedback system is used for determining a state of contact between the light exit window and the surface. To this end the feedback system is capable of detecting a feedback signal representative for the state of contact. If the feedback signal or the state of contact is such that the risk of skin surface or device damage by the device operation is too high, the user or the device has a way to interrupt the treatment or to reduce light output to reduce or eliminate this risk.Type: GrantFiled: December 27, 2017Date of Patent: May 9, 2023Assignee: Koninklijke Philips N.V.Inventors: Babu Varghese, Rieko Verhagen
