A large number of Ti atoms populated mainly on the ground state (a3F2) and metastable states (a3F3,4) were produced by UV-laser (259-300 nm) photodissociation of TiCl4. Many stimulated Raman scattering lines and stimulated radiations of Ti atoms were observed by pumping Ti atoms on the a3F2,3,4 states via nearly resonant transitions. All the lines observed were assigned. The pulse duration and timeresolved spectrum of SRS of Ti atoms shows the photolysis of TiCl4 to Ti atom was very fast, and the time estimated for it was less than Ins.
