Ultra-short pulse (Femtosecond) laser technology is becoming increasingly common withinophthalmic surgery, with all-laser LASIK eye surgery now becoming a routine procedure,available at high street opticians. However, high capital cost and limitations in performanceof traditional femtosecond laser technology are slowing down the uptake of the technology,which still only has approximately 20% of the global market for LASIK procedures. The costand performance barriers become even greater for non-elective procedures such as Cataract,especially within developing nations where clinics cannot afford high-cost instrumentation.A commercially viable, compact, cost-effective femtosecond laser technology is required toenable widespread use of laser-surgery in ophthalmology. MEGALASE will address thisneed by developing a prototype femtosecond laser delivering in excess of 20 Megawatts ofoptical peak power within pulses shorter than 500 Femtoseconds.MEGALASE is inspired by several Fianium patent applications for state of art ultrashortpulse fibre amplifier technology. The novel amplifier design delivers output power in apurely single spatial mode, offering the quality of beam that is essential for ophthalmicsurgery applications.Delivering more than 10 micro-Joules of pulse energy, the laser system output has potentialapplication within all existing elective refractive surgery procedures as well emergingprocedures including cataract repair.Successful delivery of the prototypes will present a fantastic opportunity to further exploit therapidly expanding global market for industrial and scientific laser technology to the benefit ofUK companies and the wider UK economy.

超短脉冲（飞秒）激光技术在眼科手术中越来越普遍，全激光LASIK眼科手术现在已成为一种常规手术，可在高街眼镜商处获得。然而，传统飞秒激光技术的高资本成本和性能限制正在减缓该技术的采用，该技术仍然仅占LASIK手术全球市场的约20%。对于非选择性手术，如白内障，成本和性能障碍变得更大，特别是在诊所无法负担高成本仪器的发展中国家，需要商业上可行的，紧凑的，具有成本效益的飞秒激光技术，以使激光手术在眼科中的广泛使用。MEGALASE将通过开发一种原型飞秒激光器来满足这一需求，该激光器在短于500飞秒的脉冲内提供超过20兆瓦的光峰值功率。MEGALASE的灵感来自于几项关于最先进的超短脉冲光纤放大器技术的专利申请。这种新颖的放大器设计能够以独特的单空间模式提供输出功率，提供眼科手术应用所必需的光束质量。激光系统输出在所有现有的选择性屈光手术程序以及包括白内障修复在内的新兴程序中具有潜在的应用。原型的成功交付将为进一步开发提供极好的机会。迅速扩大工业和科学激光技术的全球市场，使英国公司和更广泛的英国经济受益。
