This project aims to develop and trial a radially polarized laser for processing of materials. Methods of generating high-purity radially polarized laser modes are explored to provide seed sources for later investigation of novel amplification methods. A thermally guiding fibre-rod amplifier has been developed which is currently under trial in the amplification of radially polarized modes. The project ultimately aims to scale power levels to a level where the potential for laser processing using radially polarized modes may be explored.

该项目旨在开发和试验一种用于材料加工的径向偏振激光器。探索了产生高纯度径向偏振激光模式的方法，为以后研究新的放大方法提供了种子源。一种热导光纤棒放大器已经研制成功，目前正在对径向偏振模式的放大进行试验。该项目的最终目标是将功率水平扩大到可以探索使用径向偏振模式进行激光加工的潜力的水平。
