what does a yag laser do

The YAG laser

is the laser used to clear the frosting from the back surface of an intraocular lens. YAG laser treatment is painless and is completed from outside the eye in a few minutes. During YAG laser treatment your eye doctor may use a magnifying contact lens to help with aiming the YAG laser at the layer of frosting.

While the Er:YAG laser allows for a speedier recovery than more aggressive ablative treatments, like the CO2 laser, you’d still need about a week of social downtime as the treatment area turns darker and crusts (depending on the energy settings). Your skin could look inflamed for weeks or even months after your procedure. However, notes Dr. Tanghetti, “in the low-power mode, the erbium laser creates a superficial removal of the skin with minimal downtime.”

One advantage of the erbium laser is that, due to its high affinity for water, it can specifically target—and precisely remove—the tissue you’re treating, with minimal damage to the surrounding skin. The new skin cells that form during healing give skin a tighter, younger-looking surface. “This is an intense treatment, designed to produce dramatic rejuvenation effects,” says Dr. Butterwick.

Embrace your imperfections

YAG crystals are man-made garnets. They can be used as gemstones for jewelry, but their main use today is in the laser industry. Interestingly enough, perfect YAG crystals are useless for lasing. It is literally their imperfections that make them great.

Correction: What are YAG lasers? Plural

As mentioned earlier, yttrium aluminum garnets (YAG) must contain some impurities to be useful as a lasing material. These impurities, or dopants, come in a wide variety, including erbium (Er), neodymium (Nd), ytterbium (Yb), and many others.

Working mechanism

Nd:YAG is a 4-level gain medium. The most frequently used transition (1064 nm) is between 2 intermediate energy states. Because the lowest of these 2 energy states is usually empty at normal operating temperatures, population inversion can be attained even with low pump power. This allows for low threshold pump power and high gain efficiency.

Hazards

Nd:YAG lasers (the most widespread of YAG lasers) emit light at 1064 nm. Though light at this wavelength can damage the eye, it is invisible and hence does not trigger the blink reflex. It is therefore particularly important to respect all safety guidelines when manipulating them.

Applications

Nonetheless, if handled with care, Nd:YAG lasers can be used in medicine to destroy tumors, for cosmetic surgeries like hair and tattoo removal, as well as to correct many eye problems.

Future outlook

YAG lasers, particularly the most common Nd:YAG laser, have a bright future. They are a well-established player in the laser market with a large install base and many useful applications.
