Mulitmode optical fibres are typically used to deliver high power laser light which is emitted from the end of the fibre to irradiate tissue during surgery. For intravenous delivery of laser light in the treatment of cardiac fibrillation (heart flutter) we require a sideways-directed illuminating beam. However reliable methods of delivering high power laser light in a sideways-directed beam are not currently available. Using the ultraviolet laser fibre processing expertise already developed at Macquarie University, we propose to develop and characterise novel fibre-based devices which would allow controllable delivery of light sideways.

多模光纤通常用于递送高功率激光，该高功率激光从光纤的端部发射以在手术期间照射组织。 对于在心脏颤动（心脏扑动）的治疗中的激光的静脉内递送，我们需要侧向定向的照明光束。然而，目前还没有可靠的以侧向定向光束输送高功率激光的方法。 利用麦考瑞大学已经开发的紫外激光光纤加工专业知识，我们建议开发和验证新型光纤设备，该设备将允许可控的侧向光传输。
