The Nd:YAG laser, with its 1,064-nm wavelength, is a mainstay for treatment of vascular lesions. What it may sacrifice in absorption by hemoglobin, it makes up for in depth of penetration. The long-pulsed Nd:YAG laser has been the ideal choice for lesions off the face and for thick or deep vascular targets, although newer short-pulsed high-energy (650 ...

2009 Conference on Lasers & Electro Optics & The Pacific Rim Conference on Lasers and Electro-Optics, 2009
In this paper, the Nd: YAG laser is designed and stimulated. We considered four levels for the Nd: YAG and analyzed rate equation. With regard population inversion levels we can estimate the gain that is restricted with losses.

Review of Scientific Instruments, 2004
Laser neutralization of antipersonnel (AP) mines offers the enormous advantage to work from a safe distance. In this article the interaction of Nd:YAG laser radiation and four different types of blast AP mines is investigated. For this purpose, a very compact laser system for mine neutralization is developed.

FM-laser operation of the Nd:YAG laser
IEEE Journal of Quantum Electronics, 1970The FM-laser or frequency-sweeping mode of laser oscillation has been demonstrated in a Nd :YAG 1.06-μ laser with an intracavity LiNbO 3 phase modulator. The experimental results are in excellent agreement with the theoretical expression \Delta= (\Delta\Omega/\Delta\nu) (\delta/\pi) where δ= peak single-pass phase retardation in the modulator, \Delta ...

Optimization of the pumping conditions for Nd:YAG lasers
Applied Optics, 1990In this paper we report on the results of comparative investigations of different pump cavities. Numerical estimations of the geometrical transfer efficiency of various cavities are presented. An experimental study of the pumping efficiency and pumping uniformity of the laser heads with respect to the cavity geometry, types of flashlamp, and reflecting

Use of Nd:YAG laser capsulotomy
Survey of Ophthalmology, 2003Surgery for cataract removal has become successively refined such that posterior capsular opacification is the most common problem presenting after modern cataract extraction. Various techniques and treatments exist to manage patients with posterior capsular opacification using Nd:YAG capsulotomy.

Erbium And Holmium Lasers Pumped With Nd:YAG
LEOS '90. Conference Proceedings IEEE Lasers and Electro-Optics Society 1990 Annual Meeting, 1990Diode-pumped neodymium lasers can be used to efficiently pump other rare earth lasers. Intracavity pumping of the ytterbium-sensitized erbium phosphate glass laser gave 6% conversion of 800 nm laser diode arrays to 1.54 μm. Techniques used for pumping 2.9-μm Ho:GGG lasers are also discussed.

Nd:YAG LASER THERAPY FOR COLORECTAL POLYPS
Australian and New Zealand Journal of Surgery, 1991Adenomatous polyps are the precursors of most colonic cancers and should be removed and recovered for histological analysis. Removal by endoscopic laser photocoagulation offers a safe alternative to surgery. We report our experience of managing selected colonic polyps by neodymium: yttrium aluminum garnet (Nd:YAG) laser.

Treatment of dentin hypersensitivity by Nd:YAG laser
Journal of Clinical Periodontology, 2002AbstractBackground, aims: Promising results using Nd:YAG laser against dentin hypersensitivity have been reported. The aim of this double‐blind, controlled, split‐mouth designed clinical trial was to assess the effect of a single Nd:YAG laser application on alleviating hypersensitivity.Methods/Results: Seventeen subjects participated in the study. Each
