Laser thermal injury and subsequent wound healing in organotypic, skin-equivalent tissue models were monitored using optical coherence tomography (OCT), multiphoton microscopy (MPM), and histopathology. The in vitro skin-equivalent raft tissue model was composed of dermis with type I collagen and fibroblast cells and epidermis of differentiated keratinocytes. Noninvasive optical imaging techniq...

introduction: to improve laser hair removal (lhr) for dark skin, the fluence rate reaching the hair follicle in lhr is important. this paper presents the results of a comparative study examining the function of wavelength on dark skin types using 755 nm alexandrite and 810 nm diode lasers. methods: the structure of the skin was created using a realistic skin model by the advanced systems analys...

A non-invasive diagnostic tool that can identify diseased tissue sites in situ and in real time could have a major impact on the detection and treatment of cancer and atherosclerosis. A review of the research performed on the utilization of laser induced fluorescence spectroscopy (LIFS) as a means of diseased tissue diagnosis is presented. Special emphasis is given to problems which were raised...

FEBRUARY 2004 I CATARACT & REFRACTIVE SURGERY TODAY I 27 T he FEMTEC femtosecond (ultrashort pulse) ophthalmic laser (20/10 PERFECT VISION Optische Geräte GmbH, Heidelberg, Germany) is a photodisruptive laser. Although performed since the early 1980s, ophthalmic photodisruption has previously been limited to intraocular procedures because of the relatively large amount of energy needed to initi...

Introduction: Venous lake (VL) is characterized by vascular proliferation, clinically evidenced as а soft tumor with redbluish color. If traumatized VL are prone to hemorrhage and their treatment usually requires caution to prevent bleeding. In the last decade lasers have changed the treatment options of VL permitting the application of non-surgical techniques that reduced the hemorrhage risks ...

Lasers are making significant contributions to every step in the practice of dentistry, from diagnosis preventive measures. A laser, an acronym for light amplification by stimulated emission radiation. In recent years, improved understanding -tissue interactions and greatest importance, new technologies delivering laser tissue, has transformed into versatile valuable one. Laser is one minimally...

In this paper, we have simulated the excitation of wake fields in the interaction of an intensive laser pulses having Half-Sine and Gaussian time envelopes with a fully ionized cold plasma using particle in cell (PIC) method. We investigated the dependency of wake filed amplitude to different laser and plasma parameters such as laser wavelength, pulse duration and electron number density. In ad...
