| Summary: | 碩士 === 國立交通大學 === 電子物理系所 === 106 === The main goal of this research is to propose a new method of producing 3D visual image with high intensity 532 nm light source, and can be viewed from all 360 degrees. We use a high peak power, passively Q-switched flash-lamp laser and frequency-doubling technique, we can produce a 532 nm scattering light from laser-induced breakdown. We explore the consequence of 532 nm scattering and laser-induced breakdown by studying 90-degree spectrum and time-domain analysis. Further on, we discuss how different input energy, spot size and breakdown threshold affect focal point image and focal point image. These results show the possibility of visual-light 3D image by laser-induced breakdown.
