According to Market Research Future, the global ultrafast lasers market was valued 1.75B USD in 2021, and is expected to reach 4.48 Billion in 2028 with an estimated compound annual growth rate of 17.8% (see reference [18] of proposal). While ultrafast lasers are widely applied in academic research covering physics, chemistry, materials science, biology and medicine, this growth is driven by industrial needs where ultrashort pulses are used for manufacturing in various economic sectors including automotive, medical devices, and consumer electronics. These lasers are accurate, fast and economic tools for machining and processing materials, and are adopted to replace conventional techniques such as surgical scalpels and mechanical saws. In recent years, ultrafast laser technologies have seen a revolution: The well-established, yet complex Titanium-Sapphire (Ti-Sa) technology, providing the shortest pulses down to 20 femtoseconds with up to few tens of Watts of average power, was "dethroned". New industrial-grade turnkey Ytterbium (Yb) lasers are capable of delivering sub-picosecond pulses with kW of average power - in a highly robust and reliable manner. All major laser companies are now commercializing Yb lasers driven by scientific and industrial applications. Despite this success, a common criticism and limitation is that the pulse duration of Yb lasers is too long compared to Ti-Sa - a critical need for many applications in academia and industry. In this context, the INRS researchers have developed a novel technology capable of efficiently compressing sub-picosecond laser pulses to 10.8 femtoseconds in a simple and robust approach. With a compression ratio of nearly two orders of magnitude, this technology uses multidimensional nonlinear propagation in hollow core optical fibers filled with widely available Raman-active molecules such as nitrogen. In the context of this project, the INRS team will demonstrate this technique with state-of-the-art Yb laser systems. To enhance the value of this novel technology, they will drive coherent soft X-ray radiation with the compressed laser pulses, and will scale the technology to the visible and the mid-infrared spectral range.

根据市场研究未来，2021年全球超快激光市场价值17.5亿美元，预计2028年将达到44.8亿美元，复合年增长率估计为17.8%(见提案参考文献[18])。虽然超快激光被广泛应用于涵盖物理、化学、材料科学、生物和医学的学术研究，但这种增长是由工业需求推动的，其中超短脉冲被用于汽车、医疗设备和消费电子等各种经济部门的制造。这些激光是准确、快速和经济的材料加工和加工工具，被用来取代外科手术刀和机械锯等传统技术。近年来，超快激光技术经历了一场革命：成熟但复杂的钛蓝宝石(Ti-Sa)技术被淘汰了，该技术提供最短的脉冲，最小可达20飞秒，平均功率最高可达数十瓦。新型工业级交钥匙Yb(Yb)激光器能够以高度坚固和可靠的方式提供平均功率为千瓦的亚皮秒脉冲。所有主要的激光公司现在都在商业化由科学和工业应用驱动的Yb激光器。尽管取得了这样的成功，但一个共同的批评和限制是，与钛-Sa相比，Yb激光器的脉冲持续时间太长--这是学术界和工业中许多应用的关键需求。在这种背景下，INRS的研究人员开发了一种新的技术，能够以一种简单而稳健的方法有效地将亚皮秒激光脉冲压缩到10.8飞秒。这项技术的压缩比接近两个数量级，使用填充了广泛存在的拉曼活性分子(如氮)的空芯光纤中的多维非线性传播。在这个项目的背景下，INRS团队将用最先进的Yb激光系统来演示这项技术。为了提高这项新技术的价值，他们将用压缩的激光脉冲驱动相干软X射线辐射，并将该技术扩展到可见光和中红外光谱范围。
