Key words: Er:YAG, Er,Cr:YSGG, dental laser, hard tissue, ablation commonly used in dentistry; the Er:YAG (2940 nm) Er:YAG dental lasers utilize PFN generated pulses. Vogel A, Venugopalan V. Mechanisms of Pulsed Laser Ablatio

#Laser crystal includes Nd:YVO4、Nd:YAG、Ho:YAG、Nd:YLF、Ho:YLF、Pr:YLF、 Er:YAG、Er:YSGG、Er:Cr:YSGG、Ce:YAG、Ti:Sapphire、Er:Yb:Glass.

This study evaluated the antimicrobial efficacy of Er:YAG laser activation with photon-initiated photoacoustic streaming (PIPS), Nd:YAG laser disinfection, and conventional irrigation on Enterococcus faecalis biofilms using scanning electron microscopy (SEM). Biofilms were grown on 110 root halves and divided into the following: Groups 1 and 2 (saline and 1% NaOCl with apical position of Overall, 52.9% of patients preferred laser debridement vs. 35.3% for sharp debridement. We believe that Er:YAG laser serves as a promising technology in chronic wounds, functioning as a potentially superior alternative to sharp debridement, the current standard of therapy.

Although using Nd:YAG and Er:YAG laser in desensitization of hypersensitive teeth showed a placebo effect limited to a short time, results of this study demonstrated that both of these lasers have an acceptable therapeutic effect. PDF | On Jul 22, 2019, Maxime Lopez and others published Nd:YAG vs Er:YAG : a comparative study of laser varnish removal on easel paintings | Find, read and cite all the research you need on Photographs would also be helpful. That being said, I have both an NdYag and an Erbium:Yag laser and know the advantages and limitations of both. When used correctly in patients willing to have some downtime, the Erbium:Yag is a very good laser for under eye fine lines. Er:YAG lasers can be used in laser aided cataract surgery but owing to its water absorbable nature Nd:YAG is preferred more. Erbium YAG dental lasers are effective for removing tooth decay atraumatically, often without the need for local anesthetic to numb the tooth. Er:YAG is used for noninvasive monitoring of blood sugar.

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

With the Er:YAG and CO 2 laser, the power output must be limited so as to avoid surface damage. The reason that so many people are excited about the LMM discussed earlier is that there are a lot of stainless steel products that require laser marking and marking with a YAG laser is very expensive. YAG Laser Benefits: Engraves into metal. Faster than a CO2 laser system (when set up as a galvo system.

Effect of Nd:YAG, Ho:YAG, Er:YAG, CO 2, and GaAlAs Laser Irradiation on Surface Properties of Endosseous Dental Implants Matthias Kreisler, Dr med dent1/Hermann Götz, Dipl-Phys2/ Heinz Duschner, Univ-Prof Dr rer nat, Dr med dent habil3/Bernd d’Hoedt, Univ-Prof Dr med dent4

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). Fig. 6: Because of the higher absorption, the Er:YAG laser has a smaller penetration depth, and therefore requires less energy and less time to ablate the tissue. The shown penetration depths are for dentine. 0 200 400 600 800 1000 1200 1400 2,5 2,75 3 3,25 3,5 Wavelength (mm) Absorption (mm-1) Er,Cr:YSGG Er:YAG Er:YAG Er,Cr:YSGG 5 mm 15 mm 2005 British Association of Dermatologists • British Journal of Dermatology 2005 152, pp308–313 310 Becker’s naevus: Er:YAG vs. Q-switched Nd:YAG, M.A. Trelles et al. Regarding patients’ evaluation, treatment efficacy of the Clinical results two laser systems 1 month after surgery was rated by all patients of the two study groups as Lasers like CO2 and Er:YAG of higher wave lengths are absorbed well by water; thus, their depth of thermal damage is small, whereas lasers such as Nd:YAG are not absorbed well by water and subsequently penetrate more deeply.

This area had a surface roughness of 0.88 μm, while a smooth area between the globules had Ra of 0.20 μm. YAG laser treatments are typically only needed once as the capsule does not regrow after it is vaporised by the YAG. Complications after YAG laser are very rare but can include vitreous floaters, raised eye pressure, retinal swelling, lens damage and very rarely retinal detachment.

After crystal preparation, Er:YAG crystals should be examined by polarizing stress meter. Open the instrument and put in a crystal, then observe the phenomenon, measure and record relevant data. As shown in Figure 4, we can see that the core diameter of the crystal is 6mm, with the same size up and down.

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. 2012-06-27 The Er:YAG laser at 30 mJ/pulse and 30 Hz with water spray is capable of effectively removing plaque and calculus on the implant abutments without injuring their surfaces, indicating that the Er:YAG laser can be used for debridement of implant abutment surface. 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.
