Sir, Lumbosacral hypertrichosis is an uncommon occurrence that constitutes a significant cosmetic problem. Treatment with electrolysis is difficult and surgical excision seems to be the only permanent option. Surgery carries the risk of significant scarring and electrolysis is often impractical where a large area is affected. Recently, long-term hair removal using normal-mode ruby laser has bee...

The presence of unwanted hair continues to plague many individuals for whom traditional methods of hair removal remain unsatisfactory. Old methods of removing unwanted hair include shaving, waxing, chemical depilation, and electrolysis, all of which have temporary results. The invention of photothermolysis and the development of various laser systems with many ranges of wavelengths have made ef...

This paper deals with the experimental results of a xenon flash-lamp pumped passively Q-switched Nd:YAG laser using Cr4+:YAG saturable absorber. The need of a laser cavity to be integrated into a time-of-flight laser range finder is of great interest as an experimental investigation of several laser resonators. Two types of laser resonator, with different lengths, have been studied: the flat-fl...

Background: Hirsutism is defined as the presence of terminalhairs with a male-like pattern in women, due to the increasedlevels of androgens or increased responses of the target organs toandrogens. Facial hirsutism has a negative effect on the quality oflife in female patients. Among the many therapeutic modalitie...

Port wine stains (PWS) are the most common vascular malformation of the skin, occurring in 0.3% to 0.5% of the population. Noninvasive laser irradiation with flashlamp-pumped pulsed dye lasers (selective photothermolysis) currently comprises the gold standard treatment of PWS; however, the majority of PWS fail to clear completely after selective photothermolysis. In this review, the clinically ...

Abstract The synthesis of copper nanoparticles using a pulsed alexandrite laser is demonstrated. operated in free generation mode with pulse duration about 250 μs. target was placed distilled water and glycerin. obtained colloidal solutions were investigated by dynamic light scattering, the deposited structures studied atomic force electron microscopy. concentration depended on power radiation,...
