In this study, pure and doped TiO2 with Bi were deposited on glass substrates by pulse laser deposition (PLD) technique at a constant deposition parameter such as : (pulse Nd:YAG laser with ?=1064 nm, constant energy 800 mJ , repetition rate 6 Hz and No. of pulse (500) .These films are annealed to 523K .The structural and optical properties for thin TiO2(1-x)Bix films prepared by pulse laser deposition technique have been studied as a function of Bi content. This study shows that the films have polycrystalline structure with good identically and standard peaks for Anatase and Rutile phases. The optical studies reveal that the transition is direct with band gap value from 3.26 eV to 3.14eV with increasing of Bi content from 0 to 9 wt%.
