What wavelength is Erbium YAG laser?

What wavelength is Erbium YAG laser?

2940 nm
The erbium: YAG (Er:YAG) laser is a new addition to the armamentarium of skin resurfacing lasers. This laser, with a wavelength of 2940 nm, produces laser irradiation in the near infrared portion of the electromagnetic spectrum. This wavelength corresponds to the main peak of water absorption.

What is Erbium YAG laser used for?

Erbium-YAG lasers have been used for laser resurfacing of human skin. Example uses include treating acne scarring, deep rhytides, and melasma. In addition to being absorbed by water, the output of Er:YAG lasers is also absorbed by hydroxyapatite, which makes it a good laser for cutting bone as well as soft tissue.

What is the wavelength of the Er Cr YSGG laser?

2790 nm
There are two wavelengths, Er, Cr: YSGG at 2790 nm and Er: YAG at 2940 nm, that are similarly effective in treating soft tissue and hard tissue lesions.

What is the difference between Fraxel and Erbium laser?

Our response is that both modalities are different. The Fraxel does not resurface the entire area but is able to penetrate more deeply. The Erbium laser does not penetrate as deeply, but it is able to resurface the entire area with each treatment. The downtime associated with both is similar.

How does Erbium YAG laser work?

How does it work? The erbium laser light is absorbed by the water in your skin cells. The absorption in turn causes the instantaneous vaporization of the cell. As the laser light is passed over the skin, a mere 30 millionths of an inch of tissue is removed at a time.

Is Erbium YAG laser safe?

Post-inflammatory hyperpigmentation (PIH) was the most common side-effect as observed by Manuskiatti et al. in 92.3% patients. In our experience, PIH [Figure – 6] was low (2%) in Er:YAG ablative fractional resurfacing, suggesting that it can be safely performed in Indian skin.

Is Erbium YAG laser ablative?

The 2940 nm wavelength of Er:YAG results in ablative treatment.

Is Erbium YAG laser painful?

Thanks to the greatly limited thermal effects of Erbium lasers, Er:YAG treatments are notably less painful than CO2 lasers, and patients do not require any anesthesia when receiving treatment for small lesions.

Can YAG laser cause scarring?

This complication may have been avoided by using lower fluences, however, even with the appropriate selection of laser treatment parameters, as in this case, patients can develop cutaneous indentations. Case 5: Scarring following long pulsed 1,064 nm Nd:YAG laser treatment of excess facial hair.

What determines the wavelength of a laser diode?

The choice of the semiconductor material determines the wavelength of the emitted beam, which in today’s laser diodes range from infra-red to the UV spectrum.
