What Is Neodymium YAG Laser

Nd:YAG (neodymium-doped yttrium aluminium garnet) is a crystal that is used as a laser medium for solid-state lasers.

The triply ionised neodymium [Nd(III)] dopant (i.e. a substance added in minute amounts to another pure substance to alter its conductivity), typically replaces a small fraction of the yttrium ions in the host crystal structure, since the two ions are of similar size.

The neodymium ion provides the laser activity in the crystal.

Nd:YAG laser has a wavelength of 1064 nm and has the capability to reach deeper layers of skin tissue than other types of lasers.

What is Q-Switched / Q-Switch Nd:YAG Laser

The Q-Switched / Q-Switch Nd:YAG Laser is a type of Laser used in medical and aesthetic procedures. It works by producing short pulses of high-intensity light that are absorbed by the targeted tissue, which can be anything from pigmented lesions to tattoo inks.

In Q-switched mode, Nd: YAG produces 2 wavelengths, one in the infrared range (1064 nm) and the second beam of 532 nm wavelength which is useful for superficial skin lesions. Q-switching refers to the technique of making the laser produce a high-intensity beam in very short pulses.

The Q-Switched Nd:YAG Laser is unique in that it produces very short pulses of light (measured in nanoseconds) with very high peak power. This allows it to selectively target pigmented lesions or tattoo ink without damaging the surrounding tissue.

Additionally, the Q-Switched Laser uses a “Q-Switch” mechanism that allows it to rapidly switch on and off, producing pulses of light that are very intense and short. This helps to minimize the amount of heat that is transferred to the surrounding tissue, reducing the risk of side effects.
