INTRODUCTION Liposuction using laser is now one of the most common cosmetic surgery. This new method has minimized the disadvantages of the conventional liposuction including blood loss, skin laxity and long recovery time. Benefits of the new liposuction methods which include less trauma, bleeding and skin tightening prove the superiority of these methods over the traditional mechanical methods...

Micro-channels are made over the Ag+/Na+ ion-exchanged soda-lime glass surface by interaction of an intense Ar+ laser beam and the silver ions inside the glass matrix. The Ar+ laser beam reduces the Ag+ ions inside the matrix. The Ag+ atoms aggregate into silver nano-clusters around the interaction area, inside the glass matrix. Aggregation of the silver atoms and the thermal effects of the int...

A 40-year old woman was visited at our clinic with a history of palpable purpura appearing after alexandrite laser (Apogee 5500 Alex, 15mm spot shot, 755 nm wave length, 18 j/cm2 fluence) hair removal. The skin lesions were located bilaterally on the lower extremity (Figure1). Other physical examinations were unremarkable. The patient had no history of taking medications, underlying systemic di...

introduction: laser tissue soldering is a new technique for repair of various tissues including the skin, liver, articular cartilage and nerves and is a promising alternative to suture. to overcome the problems of thermal damage to surrounding tissues and low laser penetration depth, some exogenous chromophores such as gold nanoshells, a new class of nanoparticles consisting of a dielectric cor...

In 1960, Theodore Maiman exposed a human tooth to his prototype Ruby laser. The emission wavelength of the laser at 633 nm (deep red visible light) offered no beneficial interaction with the tooth, with much of the energy transmitting the enamel and dentine with presumable attenuation by the pigmented pulpal tissue. The inconsistencies of laser-tissue interaction continue to pose some difficult...
