WebSuch chromophores exhibit strong second- and third-order nonlinear optical properties, and polymers that contain such chromophores have found many applications ranging from laser harmonic generation,1 terahertz signal generation and detection,2 electrooptic and all-optical modulation and switching,3–5 and optical beam scanning.6 WebFeb 26, 2015 · Laser treatments are based on the principle of selective photothermolysis. Light-absorbing pigments in the skin, called chromophores, selectively absorb light energy and convert it to heat in the targeted lesions. The lesions are heated, damaged, and eliminated, while the surrounding skin is left unaffected.

WebWhat makes the skin so susceptible to laser treatment is that it contains several chromophores. These chromophores are predominantly haemoglobin, melanin, water and foreign bodies. The chromophore haemoglobin will selectively absorb light at 595nm (if using a pulsed dye laser) and the heat generated will potentially destroy the blood vessel. WebRemember back in school what chromophores were? That’s right, they are components of molecules, which absorb light. ATP is the building block. ATP is produced when the chromophores on mitochondrial membranes are stimulated. That production leads to a biological cascade of events including protein synthesis.
