At Quantum laser we use a technology called ND YAG Q switched. ND YAG stands for neodymium-doped yttrium aluminium garnet. In simple terms it means it is a crystal used as the medium in laser treatments. Q switched mode produces two wavelengths and refers to the technique of making the laser produce a high intensity beam in very short pulses. Machines without the Q switched technology cannot provide the desired results as they are not powerful enough to shatter the tattoo ink particles.

When the laser beam comes into contact with the tattoo ink it creates a photoacoustic shock wave that releases the heat from the tattoo ink and shatters it into minute particles. When this response takes place, this is known as a photo mechanical effect. Once the particles are shattered they are able to be carried away by the macrophages (the body's immune response) through the lymphatic system. This then leaves the body through the kidneys into the urine.
