Abstract:
1. A dermatological treatment method, comprising: identifying a type of dermatological lesion in an area of skin to be treated; driving a gas discharge lamp with a first current density such that the gas discharge lamp outputs a first therapeutic electromagnetic radiation which has a first spectral profile, when the area of skin is determined to have a vascular lesion; driving the gas discharge lamp with a second current density such that the gas discharge lamp outputs a second therapeutic electromagnetic radiation which has a second spectral profile, when the area of skin is determined to have a pigmented lesion, wherein the first current density is higher than the second current density so that the second spectral profile has more energy distributed at longer wavelengths than the first spectral profile; and selectively transmitting said first and second therapeutic electromagnetic radiation outputs from the gas discharge lamp through a cooled window that is in contact with the area of skin to be treated, and wherein when said first therapeutic electromagnetic radiation output is being transmitted, the window is cooled to a temperature of 5 degrees centigrade and wherein when said second therapeutic electromagnetic radiation output is being transmitted, the window is cooled to temperature between 10 and 20 degrees centigrade.
