本篇論文的研究目的是透過使用雙共振腔的數位雷射架設，令共振腔中的液晶空間光調變器的承受功率降低，同時達成模態選擇以及脈衝雷射輸出，提高數位雷射的輸出峰值功率。
本研究中，我們在次共振腔中使用液晶空間光調變器，將金屬線與輸出耦合器對光束的影響合併在投影相位板中形成數位雷射，期間，為了優化輸出場型，我們分別使用了不同形式的相位板，在旋轉投影的相位板過程中，確立了對HG10的模態選擇，同時在主腔加入聲光調變器，達成脈衝雷射輸出。

The purpose of this research is to establish a digital laser setup using a dual-cavity configuration to reduce the power load on the liquid crystal spatial light modulator(SLM) within the cavity, thereby enhancing the peak power output of the digital laser. In this study, we employed a liquid crystal spatial light modulator in the secondary cavity, combining the effects of the metal wire and the output coupler into the phase plate to generate a digital laser. To optimize the output beam profile, we utilized different forms of phase plates. By rotating the projected phase plate, mode selection for HG10 was achieved, and a acousto-optic modulator was added to the primary cavity to achieve pulse laser output.
