Background: Multi-colored and even black tattoos often require more than one wavelength to remove the target pigment. The authors
report here a novel alexandrite laser with two Nd:YAG laser handpieces pumped by the alexandrite treatment beam enabling
the delivery of three wavelengths from a single device.
Objective: To describe and evaluate the effectiveness of a novel Q-switched laser-pumped laser for treating tattoos.
Materials and Methods: Twenty tattoos in 14 subjects were treated at four-week intervals using a combination of available wavelengths
(532, 755 and 1064 nm) as determined by the treating physician. Digital cross-polarized photographs were taken before treatment
and two months following the fourth and final treatment. Photographs were evaluated by three physician observers blinded
as to the treatment condition and rated for clearance by the following scale: 1=>95 percent, 2=76–95 percent, 3=51–75 percent,
4=26–50 percent and 5=0–25 percent clearance.
Results: The average clearance score was 3.1, in the 51–75 percent range, two months following four treatments. No scarring,
hyper- or hypopigmentation was noted on post-treatment photographs or by the treating physician.
Conclusion: The alexandrite and alexandrite-pumped 532 nm and 1064 nm Q-switched lasers are effective for removing decorative
tattoos, and represents the first commercial laser with laser-pumped, laser handpieces.
