VPhD, Dentistry, Full Professor, Pontifical Catholic University of Rio Grande do Sul, Porto OBJECTIVES: CO2, Er:YAG and Nd:YAG lasers have been used in 

It encompasses two distinct approaches: the first one involves photo-thermal disaggregation of the unwanted material with an Er:YAG laser (2.94 μm) and eventually its chemical or mechanical removal while the second one involves ultraviolet laser ablation, generally with an excimer (193, 248 or 309 nm) or a high order harmonic Nd:YAG laser (213 or 266 nm).

We plan to compare fractional Er:YAG laser and long pulse Nd:YAG laser in a randomized controlled double-blind design with multiple sessions and larger sample size in comparison with previous studies. For this purpose, an Er:YAG laser (El.En LightBrush2 2.94 μm 500 mJ) and a 4th harmonic Nd:YAG laser (Quantel CFR 266 nm 50 mJ) were used. The cleaning procedure was monitored in both cases by optical microscopy, spectral domain-optical coherence tomography and UV-induced fluorescence. Nd:YAG (neodymium-doped yttrium aluminum garnet; Nd:Y 3 Al 5 O 12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant , triply ionized neodymium , Nd(III), typically replaces a small fraction (1%) of the yttrium ions in the host crystal structure of the yttrium aluminum garnet (YAG), since the two ions are of similar size.

Er:YAG lasers typically emit light with a wavelength of 2940 nm, which is infrared light. Unlike Nd:YAG laser, the output of an Er:YAG laser is strongly absorbed by water. This fact limits the use of Er:YAG laser in surgery, and in many other laser applications, to where water is present (healthy skin has a high water content). (1064 nm Nd:YAG and 2940 Er:YAG) in a three-step layering technique.

This laser works at a wavelength of 1064 nm, which has a low level  10 Jul 2007 The ubiquitous Nd:YAG laser has played many roles over the years. For the Other YAG crystals being grown in volume are Er:YAG and CTH:YAG.

Photo-thermal ablative and non-ablative fractional resurfacing and remodeling have become extremely popular due to the lower rate of Fractional Er:YAG laser and long pulse Nd:YAG laser were introduced for treating hand wrinkles. We plan to compare fractional Er:YAG laser and long pulse Nd:YAG laser in a randomized controlled double-blind design with multiple sessions and larger sample size in comparison with previous studies. For this purpose, an Er:YAG laser (El.En LightBrush2 2.94 μm 500 mJ) and a 4th harmonic Nd:YAG laser (Quantel CFR 266 nm 50 mJ) were used. The cleaning procedure was monitored in both cases by optical microscopy, spectral domain-optical coherence tomography and UV-induced fluorescence.

Erbium:YAG lasers can vary their treatment depths (full skin resurfacing vs. light Celebrity Peel). Again, the varied treatment depths of Er:YAG lasers are mostly credited to the significantly greater absorption in water found in the epidermal and dermal tissue. comparison between Er: YAG and CO2 laser was evaluated by using the pooled estimate of sensitivity and specificity. In addition, sensitivity analysis and bias analysis were applied to ensure the accuracy of the results. Results: Finally, 268 patients were enrolled in 6 studies and ultimately met the eligibility criteria. The Er: YAG and CO2 groups were 141 and 127, respectively.

Consequently, it is likely that such irregular microstructure leads to bonding failures and undermined marginal sealing. 5 REASONS WHY ERBIUM:YAG LASERS OUTPERFORM CO2 LASERS. 1. An Erbium:YAG laser wavelength is optimal for skin ablation. Erbium:YAG lasers are optimal for skin ablation primarily because of the wavelength this technology generates. Erbium:YAG is emitted at 2,940 nm, while CO 2 has a much longer wavelength at 10,600 nm. Laser rods Nd:YAG Nd:YAP Tm:YAG Tm:YAP Er:YAG Er:YAP and Yb:YAG - sales@dmphotonics.com.

The Nd-Yag laser.

The term YAG laser is usually used for solid-state lasers based on neodymium-doped YAG (Nd:YAG, more precisely Nd 3+:YAG), although there are other rare-earth-doped YAG crystals, e.g. with ytterbium, erbium, thulium or holmium doping (see below).

Neodymium, Erbium or Ytterbium doped Yttrium Aluminum Garnets (Y3Al5O12 or Nd:YAG) crystal, which continues as the best of the rare earth garnet materials 

204 As for the influence of the Er,Cr:YSGG laser on surface structure and biocompatibility of titanium implants, one essay concluded 1999-04-01 All studies included have shown that Er: YAG group was better than CO 2 group in success treatment of oral tumorous lesions. This study shows the consistent result with previous reports. In time of surgery, Er: YAG group had longer surgery time than CO 2 group. In addition, the Er:YAG laser beam does not have continuous emission and, therefore, does not provide a homogeneous etching of tooth surface, leaving non-lased areas between the pulses. Consequently, it is likely that such irregular microstructure leads to bonding failures and undermined marginal sealing. 5 REASONS WHY ERBIUM:YAG LASERS OUTPERFORM CO2 LASERS.

Er:YAG can be produced in large sizes to suit your custom laser rod requirements. Our current production capacity is 2,000 laser rods per month with the ability to increase to 10,000 laser rods per month as required. Alongside Er:YAG, we also offer Nd:YAG (Neodymium doped Yttrium Aluminium Garnet), which is available to customers on request

The dopant , triply ionized neodymium , Nd(III), typically replaces a small fraction (1%) of the yttrium ions in the host crystal structure of the yttrium aluminum garnet (YAG), since the two ions are of similar size. [1] Website. Lumibird nanosecond Q-switched Nd:YAG lasers are well known for their ruggeness and versatility. From 5 mJ to 1.5 J at 1064 nm, from single pulse to 400 Hz, they can be diode-pumped (compactness, ease of use) or flashlamp-pumped (high energy), and are available at … After Er:YAG laser application, Nd:YAG laser treatment (AT Fidelis Fotona, Ljubljana, Slovenia) was performed at an energy level of 100 mJ/pulse, and 20 Hz for removing pocket epithelium and detoxification purpose. Ytterbium – Yb:YAG emits typically at either 1030 nm (strongest line) or 1050 nm (→ ytterbium-doped gain media ). It is often used in, e.g., powerful and efficient thin-disk lasers. Erbium – Pulsed Er:YAG lasers, often lamp-pumped, can emit at 2.94 μm and are used in, e.g., dentistry and for skin resurfacing.

Energy source. The energy source or pump source supplies energy to the active medium to achieve population inversion. In Nd: YAG laser, light energy sources such as flashtube Er YAG laser Crystal—50% Erbium doped in YAG which can stimulate 2940nm laser used in medical and dentistry The emission wavelength of Er YAG with doping concentration of 50% is 2940nm, which is at the position of water absorption peak and can be strongly absorbed by water molecules. 2021-03-04 The mechanical properties of Er:YAG are essentially the same as Nd:YAG. Er:YAG operates at wavelengths where the threshold for eye damage is relatively high (since the light is absorbed before striking the retina), works well at room temperature, and has high slope efficiency. Er:YAG is pale green. Er:YAG can be produced in large sizes to suit your custom laser rod requirements.
