Method of hair depilation

摘要

A method of hair depilation using an Nd:YAG laser which causes local heating at the hair bulb due to the absorption of the oxyhemoglobin contained in the capillaries. The Nd:YAG laser operates at 1060 nanometers. Each pulse is a special pulse having a first portion and a second portion, where power output in the first portion is 20 times greater than power output in the second portion. That way, the first portion of each pulse is used to quickly heat up the tissue to a damaging temperature, and the second portion maintains that temperature to cause hair removal for the tissue.
