Comparison of pulsed dye laser versus combined pulsed dye

SpletThe Vbeam laser system is a pulsed-dye laser indicated for dermatological applications. It delivers pulsed laser energy at a wavelength of 595 nm that passes through the dermis and epidermis skin layers and is absorbed by the oxyhemoglobin in the blood vessels rather than by the surrounding tissue.
