摘要：
A light-based skin treatment device is for treating skin by laser induced optical breakdown of hair or skin tissue. A focusing system has an exit focusing lens for focusing the incident light beam into a focal spot in the hair or skin tissue. This lens has a central aperture. This serves to reduce back-reflectance from the lens surface, which can cause damage to the focusing system.
