Comparison of 585 nm with 595 nm pulsed dye laser in the treatment of warts
Background and aim : The clinical management of verrucae vulgaris is often challenging and no treatment is always effective. Early studies have suggested that pulsed-dye laser (PDL) may be highly effective in the treatment of verrucae through obliteration of dilated vessels in papillary dermis. The objective of this study was to compare safety and efficacy of 585 nm with 595 nm PDL in the...
متن کاملTheoretical investigation on thermal responses of Port Wine Stain lesions to 585 nm , 595 nm and 1064 nm lasers
As a kind of congenital vascular malformations, Port Wine Stain (PWS) is composed of ectatic venular capillary blood vessels buried within healthy dermis. In clinic, Pulsed Dye Laser (PDL) in visible band (e.g. 585 or 595 nm) together with cryogen spray cooling has become the golden standard for treatment of PWS. However, due to the limited energy penetration depth of the PDL, deeply buried blo...
متن کاملAbsolute-Frequency Measurement of the Iodine-Based Length Standard at 514.67 nm
The absolute frequency of the length standard at 514.67 nm based on the molecular iodine ( I2) transition of the P(13) 43-0 component a3 is measured using a self-referenced femtosecond optical comb. This frequency-based technique improves measurement precision more than 100 times compared with previous wavelength-based results. Powerand pressure-related frequency shifts have been carefully stud...
متن کاملAbsolute Frequency Measurement of the Iodine-Stabilized Heâ‹TMNe Laser at 633 Nm
The absolute frequency of an iodine-stabilized He−Ne laser at 633 nm stabilized on the i (or a13) component of the 11-5 R(127) hyperfine transition of the I2 molecule is measured using a femtosecond optical comb generator and an iodine-stabilized Nd:YAG laser standard at 1064 nm. We link the measured absolute frequency to the current internationally adopted value via frequency intercomparison b...
متن کاملProspective study of port wine stain treatment with dye laser: comparison of two wavelengths (585 nm vs. 595 nm) and two pulse durations (0.5 milliseconds vs. 20 milliseconds).
BACKGROUND AND OBJECTIVES The conventional pulsed-dye laser (wavelength 585 nm, pulse duration 0.5 milliseconds) is seen as the standard treatment for port wine stains (PWS). Using the pulsed-dye laser at wavelengths of 590, 595, and 600 nm and at varying pulse durations of 1.5-40 milliseconds is one of the newest developments in the field, the therapeutic value of which has been examined in on...
