Q-switched 532nm laser energy causes significant vascular damage in the capillary plexus – how does this affect laser tattoo removal?

Abstract

Tattoos can be effectively removed using Q-switched and picosecond lasers at four wavelengths – 1064, 755, 694 and 532nm1,2,3,4. However, there are two particular problems with the 532nm line. Firstly, it is well absorbed by the melanin in the epidermis, due to its relatively high absorption coefficient5, (μa_mel = 56 cm−1 for typical Caucasian skin). Secondly, 532nm is also strongly absorbed in the haemoglobin located in the capillary plexus5a_HbO = 260 cm−1).
