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.

据Market Research Future预测，2021年全球超快激光器市场规模为1.75B美元，预计2028年将达到44.8亿美元，预计复合年增长率为17.8%（参见提案参考文献[18]）。虽然超快激光器广泛应用于涵盖物理、化学、材料科学、生物学和医学的学术研究，但这种增长是由工业需求推动的，其中超短脉冲用于汽车、医疗设备和消费电子等各个经济领域的制造。这些激光器是用于机械加工和加工材料的精确、快速和经济的工具，并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“废黜”，该技术可提供低至 20 飞秒的最短脉冲和高达几十瓦的平均功率。新型工业级交钥匙镱 (Yb) 激光器能够以高度稳健和可靠的方式提供平均功率为 kW 的亚皮秒脉冲。目前，所有主要激光公司都在科学和工业应用的推动下将镱激光器商业化。尽管取得了这一成功，但一个常见的批评和限制是，与 Ti-Sa 激光器相比，Yb 激光器的脉冲持续时间太长，而 Ti-Sa 激光器是学术界和工业界许多应用的关键需求。 在此背景下，INRS 研究人员开发了一种新技术，能够通过简单而稳健的方法将亚皮秒激光脉冲有效压缩至 10.8 飞秒。该技术的压缩比接近两个数量级，在填充有广泛使用的拉曼活性分子（例如氮）的空心光纤中使用多维非线性传播。在该项目中，INRS 团队将使用最先进的 Yb 激光系统演示这项技术。为了提高这项新技术的价值，他们将用压缩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。
