The Q-switched Nd:YAG laser（single pulse 800mj) radiates the light with a specific wavelength in high peak energy pulses, hence the light penetrates into the tissue only for a nanosecond. The light is absorbed by the pigmentation and results in an instantaneous blast, that is Light blasting principle. The pigmentation particles are shattered into fragments, some can be bounced out of the skin and others can be splited into tiny particles that can be engulfed by phagocytes and then eliminated by the lymphatic system.
