There are few known alternatives to the use of high-peak power sub-nanosecond lasers for high quality laser manufacturing and surgery applications. This project plans to explore the use of ultrafast all-optical shutters and their use for non-thermal ablation by further developing an ultrafast all-optical shutter. The shutter allows sampling of high-peak power nanosecond laser pulses to produce high-peak power picosecond or femtosecond pulses that are well suited for non-thermal ablation of materials. This technology can operate across a wide spectral range. It can directly modulate high peak-power lasers and offers the ability to continuously tune the shutter's time window width. The ultrafast all-optical shutter technology offers a novel approach towards producing sub-nanosecond optical pulses. Ultrafast laser pulses are finding an ever increasing range of applications in medicine, manufacturing, and technology as a whole. This technology has the potential to impact laser manufacturing and laser surgery by allowing replacement of expensive high peak-power sub-nanosecond lasers with less expensive nanosecond lasers combined with an ultrafast all-optical shutter; thereby, significantly decreasing the capital equipment and recurring cost for high-quality pulsed laser manufacturing and laser surgery. The increasing use of ultrafast lasers for the non-thermal ablation of materials in the areas of laser manufacturing and laser surgery combined with widespread use of this technology has the potential to make non-thermal laser ablation affordable for a wider range of customers.

对于高质量的激光制造和外科手术应用，几乎没有已知的高峰值功率亚纳秒激光器的替代品。该项目计划通过进一步开发超快全光学快门来探索超快全光学快门的使用及其在非热消融中的使用。快门允许对高峰值功率纳秒激光脉冲进行采样，以产生非常适合于材料的非热烧蚀的高峰值功率皮秒或飞秒脉冲。这项技术可以在很宽的光谱范围内工作。它可以直接调制高峰值功率激光器，并提供连续调整快门时间窗口宽度的能力。超快全光快门技术为产生亚纳秒光脉冲提供了一种新的途径。超快激光脉冲在医学、制造业和整个技术领域的应用范围越来越广。这项技术有可能影响激光制造和激光手术，因为它允许用较便宜的纳秒激光器与超快全光学快门相结合来取代昂贵的高峰值功率亚纳秒激光器;从而显著降低高质量脉冲激光制造和激光手术的资本设备和经常性成本。在激光制造和激光手术领域，越来越多地使用超快激光进行材料的非热烧蚀，加上该技术的广泛使用，有可能使更广泛的客户能够负担得起非热激光烧蚀。
