We have developed a simplified version of the side-pumped pulsed dye laser which has a spectral halfwidth of 1.25 GHz and a peak power of 10 kW at 600 nm. The basic laser consists of only four components (output mirror, dye cell, diffraction grating, and tuning mirror) and is exceptionally easy to align. Since the beam expander has been eliminated, the laser cavity can be made quite compact. Un...

BACKGROUND To our knowledge, no systematic analysis of nonablative laser therapy has been performed. OBJECTIVE To alter the parameters (fluence, spot size, pulse duration, and use of cooling spray) for the pulsed dye laser to determine the precise settings that would yield the most favorable dermal remodeling in a porcine model. METHODS Research was conducted in an animal laboratory at Alba...

Granuloma faciale (GF) is a rare cutaneous disorder categorized as a localized form of small-vessel vasculitis. Clinically, it manifests as single or multiple well-demarcated red-brown plaques, papules and nodules, nearly always confined to the face. Herein, we report a 39-year-old man with multiple red-brown infiltrated plaques on face and extrafacial lesions on back, shoulders and both arms. ...

UNLABELLED BACKGROUND OF OBJECTIVE: Treatment of xanthelasma palpebrarum may prove difficult due to its delicate location at the periorbita and its sometimes extensive dimension. During recent years, carbon dioxide and argon lasers have been used with good results. However, local anesthesia is always required, and there is a concrete risk of scarring and pigmentation changes after the treatment...

Fluorescence photobleaching was measured in dye-impregnated sol–gel/polymer composite glasses. These fluorescent glasses were used as the gain medium in a transverse-pumped solid-state dye laser. In this configuration, the fluorescent glass was excited by a pulsed Nd:YAG laser (about 6 mJ/pulse) either while placed in an optical cavity (i.e., functioning as a pulsed laser) or with the optical c...

Angioma serpiginosum (AS) is a nevoid capillary malformation developed congenitally or thereafter. The AS stops growing after puberty and may remain persistent throughout life. The pulsed dye laser (PDL) and KTP are used to treat the AS usually after several sessions. We treated a patient with AS with only one session of intense pulsed light (IPL) therapy. A 40-year-old lady with Fitzpatrick sk...

PURPOSE To determine the most appropriate time for laser irradiation to produce selective occlusion of new corneal vessels by photodynamic therapy (PDT) with a new photosensitizer, ATX-S10(Na). METHODS The time course of the plasma levels of ATX-S10(Na) and the degree of dye accumulation in the corneal neovascularization after intravenous administration was determined in rabbit eyes. Plasma c...

BACKGROUND AND OBJECTIVES Many laser, light and energy emitting devices are utilized for skin rejuvenation. STUDY DESIGN/MATERIALS AND METHODS The clinical approach to multiple problems of photoaging are discussed and an algorithm for approach by problem is presented. RESULTS Clinical use of various modalities such as LED photomodulation, intense pulsed light, pulsed dye laser, KTP laser, r...
