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

该项目将开发两种新的低成本离子注入技术，将基于玻璃的可饱和吸收‘Q开关’(SAQS)功能集成到用于1.5微米激光的激光棒中(GMS已经为该市场开发了一种激光棒材料)。这两种方法都避免了制造单独的SAQS组件的需要，避免了由于组件未对齐而导致的模块返工的进一步成本和风险。将Q开关集成到激光棒中还消除了激光腔内的两层高成本抗反射涂层(一层在激光棒上，一层在Q开关上)，并缩小了激光发射器的尺寸。

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.
