Development of Glass-based Saturable Absorber Q-Switch (Glass SAQS) technology

该项目将开发两种新颖的低成本离子注入技术，将玻璃基可饱和吸收体“Q开关”（SAQS）功能集成到1.5 μm激光器的激光棒中（GMS已经开发了激光棒材料）。这两种路线都避免了制造单独的SAQS组件的需要、进一步的成本以及由于组件未对准而导致的模块返工的风险。将Q开关结合到激光棒中还消除了激光腔内的两个高成本抗反射涂层（一个在激光棒上，一个在Q开关上）并且减小了激光发射器尺寸。

This project will develop two novel, low cost ion-implantation techniques to integrate glass-based saturable-absorber ‘Q-switch’ (SAQS) functionality into a laser rod for 1.5 µm lasers (a market for which GMS has already developed a laser rod material). Both routes avoid the need for manufacturing a separate SAQS component, further costs and risk of module rework due to misalignment of components. Incorporation of the Q-switch into the laser rod also eliminates two of the high-cost antireflective coatings within the laser cavity (one on the laser rod, one on the Q-switch) & reduces the laser transmitter size.
