The first ever production picosecond‐domain laser with a 785 nm wavelength was recently developed to improve the rate of clearance of green, blue, and purple tattoo inks – often the colors most resistant to laser removal.
A clinical trial published in Lasers in Surgery and Medicine (LSM), the official journal of the American Society for Laser Medicine and Surgery Inc (ASLMS), investigated the safety and efficacy of the new 785 nm Ti-Sapphire laser for treating blue, green and purple tattoo inks as an addition to a picosecond-domain 1,064 nm and 532 nm laser platform. This first study of a new, 785 nm, picosecond-domain, laser-pumped-laser demonstrates safe and effective removal of multicolor tattoos.
The study, conducted by Eric F. Bernstein, MD, Jayant Bhawalkar, PhD, and Kevin T. Schomacker, PhD, titled “A Novel Titanium Sapphire Picosecond-domain Laser Safely and Effectively Removes Purple, Blue and Green Tattoo Inks,” was selected as Editor’s Choice in the September 2018 issue of LSM.
“The laser-pumped-laser concept enables delivery of multiple discrete wavelengths from a single laser platform. A commercial 785 nm Ti-Sapphire laser has been a long time coming,” Bernstein says. “Having a picosecond-domain version for treating blue, green and purple tattoos is a big advantage.”
