For Nd:YAG lasers operating in the power range of 1 kW the problem of penetration control is overcome by the use of Ar + 20% CO 2 or Ar + (1-2)% O 2 as the shielding gas, however slight oxidation of weld metal may be caused by them. Helium can also be used with Nd:YAG laser but it is reported to cause more weld porosity than with the use of OFN.

Helium can also be used with Nd:YAG laser but it is reported to cause more weld porosity than with the use of OFN. In the present case, combination treatment with intense pulsed light (IPL) and erbium:yttrium-aluminum-garnet (Er:YAG) laser was used, and its effectiveness was evaluated. A 56-year-old man with a CMN on the left malar area was treated with combined IPL and Er:YAG laser treatment once monthly. Uninovia by Laser Er:Yag, Cogny, Rhone-Alpes, France. 40 likes.

An Er:YAG laser is used to make one pair of 4.5 mm incisions in each quadrant, starting 0.5 mm from the limbus with a separation of 2.5 mm and a depth of about 75% of the sclera. The Er.YAG laser was a development of the carbon dioxide laser technology. Also otherwise known in its full form as the ‘ erbium: yttrium aluminium garnet ’ laser, it is the only one lasers approved by the Food and Drug Authority of United States for dental cleaning and bone surgery Between 2.6 μm and 2.8 μm the absorption of water is still stronger than at 2.94 μm (Er:YAG laser) which makes lasers working in this wavelength range (e. g. the Er:Cr:YSGG laser) promising candidates for future applications.

With shallow peri-implant bony defects, the Er:YAG laser sterilization rates were model mimicking various peri-implant intra-bony defects of root-form implants 

Objective: The aim of this study was to evaluate the in vitro effects of Er:YAG laser and an in-office desensitizing paste alone or in combination by using scanning electron microscopic (SEM) analysis.Background data: Various treatment modalities have been proposed for dentin hypersensitivity, but to date, no single agent or form of treatment has been found effective. laser types used in dentistry, Er:YAG and Er,Cr:YSGG laser devices have performed best with use in dental hard tissues, as their wavelengths are close to the peak with respect to the hydroxyl groups and water absorp-tion [9, 10].

Er:YAG lasers can also be operated on the 4 I 13/2 → 4 I 15/2 transition, then emitting around 1.645 μm. Efficient operation can be achieved by in-band pumping e.g. with an erbium-doped fiber laser emitting at 1.53 μm.

The Er:YAG laser with SMA module may be considered as a novel and effective technique to treat SD lesions with minimal time recovery.

The Erbium Yag does not produce as much heat and penetrates only about 20 percent as deeply as CO2 lasers. They are used to treat wrinkles and scars that are less severe; treatments are less painful and produce fewer side effects. You’ll need about a week of recovery time. The Erbium Yag Laser is most commonly used for:

The results support the idea of continuous, thermally driven microexplosion type of ablation, which is based on the inhomogeneous distribution of strong (water) and weak absorbers (hydroxyapatite).
