  • LIOB based hair cutting device
    Patent number: 9622818
    Abstract: A laser-based hair cutting device (10) comprises a laser source (18), an optically transparent exit window (15) and optical elements (11, 12, 13, 14). The laser source (18) provides an incident light beam (21) for cutting a hair (22) above and near a skin surface by laser-induced optical breakdown (LIOB) of the hair (22) in a focal position of the light beam (21). The optically transparent exit window has an external exit surface (15) for allowing the incident light beam (21) to leave the device. The optical elements (11, 12, 13, 14) focus the incident light beam (21) in the focal position at a working distance from the exit surface (15).
