The relationship between the reflection coefficient of human skin at a wavelength of 980 nm and its temperature during exposure to laser radiation of the same wavelength has been measured for the first time in an in vivo experiment. An interpretation of the experimentally obtained results is provided within the framework of a seven-layer optical computer model of human skin. Association of the observed alteration in the reflection coefficient at the wavelength of 980 nm to the conversion of skin blood hemoglobin into methemoglobin is demonstrated. The results of this research may find application in the development of novel laser systems with feedback mechanisms and technologies for treating dermatological conditions, including telangiectasias.
