Clinical applications of Q-switched NdYAG laser.

682 infrared range of the electromagnetic spectrum. Though all these lasers would have some effect on melanin, three wavelength bands are most useful for treating pigmented lesions – green, red, and infrared.[1] Its not only about the wavelength, it is more about the right pulse duration and at sufficient fluence. Since green and blue light lasers are long pulsed continuous waves, they cause a lot of damage to surrounding skin. However, in the last decade, the Q-switching technique has given birth to Q-switched ruby, Q-switched alexandrite, and in the infrared category, Q-switched NdYAG laser.
