  • Abstract


    The spectral properties absorption of laser dyes (C480 & R610) mixture have been studied; this type of laser dye belongs to the coumarinoids and Xanthenes family, and has been dissolved  in  ethanol  to  prepare  (1:1,  1:2,  1:3,  1;4,  ratio)  from  Cumarin  480(C48): Rohdamin

    610 (R610) in (10-4 10-5 ,10-6 ) M/L concentration  at room temperature. The achieved results pointed out to an increase in the absorption   intensities with the increased concentration of R610 from(10-6,10-5  to 10-4   M/L the same thing for C480 which are found in agreement with Beer – Lambert law and theachieved Results pointed that the absorption peak are moving toward short wavelengths

    (BLUE SHIFT) when increasing the ratio of concentration.
