本論文的研究目的是透過模擬及實驗探討在數位雷射中使用單點高斯光束為最小單位，透過多點高斯光束的疊加，於數位雷射中產生各類的目標光束。本研究中透過改變雷射共振腔內空間光調變器投影的相位資訊，可於雷射共振腔腔內，生成具有任意指定場型的光束。首先，架設出L型數位雷射，詳細討論影響生成任意光場的各個重要參數，並且 利用高斯光束疊加生成各種強度均勻光場以及強度連續變化的光場。透過本論文的研究，利用數位雷射產生了各類具有任意場型的光場，包含了:能量呈均勻分布的矩形、三角形、T字型雷射光束和強度呈連續變化分布的傾斜矩形光場、三角錐、四角錐、圓球能量分布光場 ，以及環型陣列光場。研究結果發現實驗結果均與模擬計算中的預測非常相似，使用高斯光束疊加的方法確實能有效的於數位雷射中生成任意場型。本論文之研究成果將有益於各類結構光束之研究及應用。

The purpose of this research is to generate an arbitrary beam only by designing the phase information projected on the spatial light modulator (SLM) to change the boundary conditions of the laser cavity. This study provided a way that beams with any specified field, superposition of multiple Gaussian beams, can be generated in digital laser. In this thesis, we demonstrated the triangular, square, T-shaped uniform energy distribution laser beams and compared the experimental results with the prediction of simulation. Furthermore, the superposition of multiple Gaussian beams with different amplitudes also can generate a continuous distribution light field with different intensity, including pentahedron, tetrahedron, and sphere energy distribution light field. The consequences of this examination could be profitable in numerous territories, for example, optical tweezers, lithography, photopolymerization, material processing, and different applications.
