Experimental measurements using dye lasers

in this thesis ,we studied the effect of changing the concentration of rhodamin 101 (rh 101)dye solutions on its fluorescence intensity.the dye solution is pumped by pulesd nitrogen laser of wavelength 337 nm the rh 101 concentration was studied from the range of 10m/l to 5*10 m/l in pure ethanol...in this thesis ,we studied the effect of changing the concentration of rhodamin 101 (rh 101)dye solutions on its fluorescence intensity.the dye solution is pumped by pulesd nitrogen laser of wavelength 337 nm the rh 101 concentration was studied from the range of 10m/l to 5*10 m/l in pure ethanol.text in english, abstract in English and arabic
