What is a Chromophore & Why is it Important in Laser …

A chromophore is the part of a molecule responsible for its color. The color that is seen by our eyes is the one not absorbed by the reflecting object within a certain wavelength spectrum of visible light. The chromophore is a region in the molecule where the energy difference between two separate molecular orbitals falls within the range of the visible spectrum. Visible light that hits the chromo… WebThe KTP laser works on the principle of selective photothermolysis. The selected wavelength of laser light is absorbed to a high degree by the target structure (called a chromophore) and is absorbed less by surrounding tissue. The skin chromophores targeted by the KTP laser are melanin, oxyhaemoglobin and red tattoo pigment. highlander all wheel drive https://eastwin.org
