Optical limiting properties of sudan red B in solution and solid film

The optical limiting performance of sudan red B is described in solution and in the solid state. The measurements were performed using a cw solid state laser. Parameters of optical limiting properties such as the threshold and saturated values can be engineered by modifying the parameters of the set-up and the concentration of the sample. It has been found that the limiting efficiency for sudan red B doped polymerthyl methacrylate (PMMA) is better than in sudan red B in the solvent toluene sample. The sudan red B doped PMMA exhibits good optical limiting features at 532 nm with the limiting threshold of 5.8 mW. The present studies suggest that polymer film is a potential candidate for optical device applications such as optical limiters.
