Abstract:
A method and system of ablating melanin are provided. Stepwise multi-photon fluorescence is induced in melanin within a region of tissue. The fluorescence is detected, and at least a portion of the melanin from which the fluorescence is detected is ablated. The system and method can use a continuous wave laser in the near infrared range for the inducement and ablation of melanin, providing high resolution at low cost.
