In addition to conventional treatment modalities (mechanical and chemical), the use of lasers has been increasingly proposed for the treatment of periodontal and peri-implant infections (i.e., cleaning and detoxification of implant surfaces). Preliminary results from basic studies have pointed to the high potential of the Erbium-doped: Yttrium, Aluminum and Garnet (Er:YAG) laser. Furthermore, p...

A reduction of more than 20 dB of the intensity noise at the antiphase relaxation oscillation frequency is experimentally demonstrated in a two-polarization dual-frequency solid-state laser without any optical or electronic feedback loop. Such behavior is inherently obtained by aligning the two orthogonally polarized oscillating modes with the crystallographic axes of a (100)-cut neodymium-dope...

Laser-assisted lipolysis with a medium-pulsed 1064-nanometer neodymium-doped yttrium aluminum garnet (Nd:YAG) system is a new FDA-approved method of removing localized areas of fat with the added benefit of skin tightening. This new method is particularly useful in treating the lower abdomen and submental areas where skin laxity may occur after the removal of adipose tissue. In addition, decrea...

Percutaneous holmium yttrium aluminum garnet (Ho:YAG) laser ablation of the nucleus pulposus of thoracolumbar discs in dogs as a prophylactic procedure for prevention of catastrophic intervertebral disc protrusion/extrusion has been utilized at Oklahoma State University Center for Veterinary Health Sciences (CVHS) since 1992. Over 400 animals have been treated using percutaneous laser disc abla...

Fibrosing mediastinitis is underdiagnosed because of the nonspecific character of the presenting symptoms. The endobronchial findings obtained via flexible bronchoscopy are not defined in the literature. We describe 3 cases of fibrosing mediastinitis, most likely caused by histoplasmosis. All 3 patients presented with hemoptysis and were found to have tracheobronchial concentric narrowing, seve...

A laser-induced optical force trap was used to alter the movement of chromosomes in mitotic cells in vitro. The trap was produced by using a 1.06-microns neodymium YAG (yttrium/aluminum garnet) laser focused through a phase-contrast microscope. The trap was applied to one side of centrophilic chromosomes off the mitotic spindle and to late-moving chromosomes on the mitotic spindle. In both situ...

Laser emission from neodymium-doped glass was first produced nearly 40 years ago. Later, a crystal of yttrium, aluminum, and garnet (YAG) was discovered to be a better lasing host for neodymium. The Nd:YAG laser has since been used for a variety of medical applications, more recently, this instrument has been used for the purpose of damaging hair follicles to epilate unwanted hair. This article...

Rhythmic bursting on the order of seconds in a cluster of plastic beads under continuous irradiation of a focused neodymium-doped yttrium aluminum garnet (Nd:YAG) laser beam (1064 nm) is reported. The oscillatory instability is induced as a result of competition between trapping and scattering forces, where both forces are induced by the focused laser beam. Above a critical power of the laser b...

Background: Endoscopic treatment of ureteral strictures provides a minimally invasive approach with shorter hospital stay and less postoperative pain. There are different therapeutic options, the dilatation balloon endoureterotomy holmium yttrium-aluminum-garnet (Ho:YAG) laser most used. To assess histological changes after in stricture comparing Ho:YAG versus endoureterotomy.
