The third order nonlinear properties and optical limiting behavior Pyronin-Y dye was studied by using Z-scan technique. The pulsed Nd:YAG laser of wavelength 532 nm is used as a source of excitation. The experimental results showed that the Pyronin-Y dye exhibited saturation absorption and negative nonlinearity. The nonlinear refractive index n2, nonlinear absorption coefficient β and third order nonlinear optical susceptibility χ3 were measured for different concentrations of dye in ethanol. This shows that the dye has potential application in nonlinear optics..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
