Optical limiting behavior of disperse red 1 dye doped polymer

Measurements of optical limiting response in disperse red 1 dye doped into ethylene propylene diene polymethylene polymer (EPDM) are reported using 532 nm wavelength, 10 ns pulses from a frequency-doubled Nd-YAG laser. The optical limiting behavior of the dye doped polymer was studied by transmission measurement technique at various concentrations. The results reveal that the optical limiting efficiency is dependent on concentration.
