Abstract

A random laser has been produced using Fluorescein dye solution in water, with concentration of (8 10^-5 M); doped with (0.001g) TiO₂ Nanoparticles with the particle size of (15.7 nm). A blue diode laser of 450 nm wavelength has been used as an optical pumping source. The wavelength of the random laser was 523 nm and the intensity was 5.44 mW
