“…In order to calculate the heating of a vessel by the CVL radiation, the skin treatment technique was employed, which envisaged using the YakhromaMed CVL device in the treat ment of telangiectasias [2]. The average power was 0.6-0.8 W, exposure time 0.2 s, repetition rate 16.6 kHz, duration of pulse generation 15 ns and size of the light spot on the skin 1 mm, which corresponds to an energy exposure density (fluence) of 15-20 J cm −2 .…”
