Abstract: The present invention relates to a pulsed laser deposition system, and particularly relates to a pulsed laser deposition system capable of using several different targets. In the pulsed laser deposition system, a beam-splitting device is provided to split a UV laser beam into several UV laser beams and to introduce these UV laser beams to different targets simultaneously. Therefore, the pulsed laser deposition system can use several different targets and can be used to form doped epitaxial layer (III-V semiconductor film) and ternary or quaternary epitaxial layer (III-V semiconductor film).
