Many patients accept the surgical treatment for tattoos only because the social stigma of the tattoo is of greater hindrance than the scarring.

The laser is uniquely adapted for this surgical problem. Emitting a brief (8 to 10 nanosecond (nsec) Q-pulsed; 1.8 msec long pulse) narrow band (6,943 Angstroms) of high energy light (100 megawatt), the ruby laser beam, as any light, is absorbed more by dark substances than by light substances. A large amount of laser energy is delivered accurately to the target area and one is able to capitalize on the differential uptake of light energy by dark versus light materials.
