Fractional Carbon Dioxide, Long Pulse Nd:YAG and Pulsed Dye Laser in the Management of Keloids
BACKGROUND Keloids are abnormal wound responses characterised by excessive deposition of collagen and glycoprotein. They are both aesthetically and symptomatically distressing for most of the patients. There are reports of keloid management with pulsed dye laser (PDL), fractional carbon dioxide (CO2) laser and neodymium-doped yttrium aluminium garnet (Nd:YAG) laser individually and also in comb...
متن کاملA Long Pulse Discharge Excited ArF Laser
An X-ray preionised, discharge excited ArF excimer laser, = 193 nm, has been studied in the long pulse regime. The laser performance is found to be primarily dependent on the discharge stability, and therefore, on the gas composition, preionization timing and the pumping power. Using X-ray preionization and prepulse-mainpulse excitation, laser pulselengths of up to 120-ns full-width at half-max...
متن کاملThe effects of pulse dye laser double-pass treatment intervals on depth of vessel coagulation.
BACKGROUND AND OBJECTIVE Multi-pass treatments with pulse dye lasers (PDLs) are avoided due to perceived side effects. Proper multi-pass techniques allow for deeper vascular injury. New extended PDLs allow use of multi-pass procedures. This study evaluates how the time between pulses, inter-pulse interval [IPI] affect extent of vascular treatment. STUDY DESIGN/MATERIALS AND METHODS Sixteen su...
متن کاملUse of a novel pulse dye laser for rapid single-pass purpura-free treatment of telangiectases.
BACKGROUND Purpura-free elimination of telangiectases with a single pass of a pulsed dye laser with a large spot has proved difficult. OBJECTIVE The purpose of this report was to define parameters that achieve single-pass purpura-free telangiectasia reduction. MATERIALS Thirty patients between the ages of 23 and 78 years were treated with a pulsed dye laser with a 10-mm spot and fluences ra...
متن کاملLong-pulse KrCl laser with a high discharge quality
The discharge quality and optimum pump parameters of a long-pulse high-pressure gas discharge excited KrCl laser are investigated. A three-electrode prepulse–mainpulse excitation circuit is employed as pump source. The discharge volume contains a gas mixture of HCl/Kr/Ne operated at a total pressure of up to 5 bar. For a plane–plane resonator, the divergence of both output laser beams is measur...
