The Nd:YAG is a popular laser that emits light at the far end of the infrared spectrum, 1064 nm. Like the others, it has been used to remove tattoos [24], hair epilation [25], skin

resurfacing [26] and treatment of varicose veins [27]. The penetration of light at 1064 nm is believed to be deeper than the ruby, alexandrite, or diode lasers. Further, the lower energy wavelengths have a lower potential to elicit adverse effects. However, the efficacy of Nd: YAG compared to the other lasers is thought to be “less” because of its lower absorption intensity for the melanin chromophore.
