introduction:  no modality has been identified as the treatment of chice for treating common warts. cryothearpy and pulsed-dye laser (pdl) are among common modalities for treating these lesions. the aim of this study was to compare pulsed dye laser with cryotherapy in terms of efficacy and complications. methods:  of a total of 46 patients enrolled in this study, 7 patients withdrew the study, ...

Laser treatment of vascular skin lesions is rapidly improving. Port wine stain (PWS) is one of the first lesions successfully treated with laser. The pulsed dye laser (PDL) has been developed on the concept of selective photothermolysis and has revolutionized PWS treatment. Even though the response is variable, substantial blanching can be obtained after several sessions. Greater selectivity an...

High-definition patterns were observed under 10-Hz-pulse-repetition-rate, nanosecond laser irradiation of azodye-doped planar-nematic liquid crystal layers at incident intensities I 5–10 MW=cm in a single beam configuration and without any feedback involved. An incident polarization parallel to the nematic director was used. Under periodic pulsed laser irradiation, far-field beam patterns at th...

Discoid lupus erythematosus (DLE) is a chronic form of cutaneous lupus that can cause permanent scarring. Treatment of DLE includes protection from sunlight and artificial sources of ultraviolet light, as well as systemic and topical medications. The first-line standard therapies are antimalarials and topical steroids. Other systemic therapies include systemic steroid, azathioprine, dapsone, an...

This paper presents wavelength configurable on-chip solid-state ring lasers fabricated by a single-mask standard lithography. The single- and coupled-ring resonator hosts were fabricated on a fused-silica wafer and filled with 3,3'-Diethyloxacarbocyanine iodide (CY3), Rhodamine 6G (R6G), and 3,3'-Diethylthiadicarbocyanine iodide (CY5)-doped polymer as the reconfigurable gain media. The recorded...
