项目摘要
Within the recent years, ultrafast lasers based on chirped pulse amplification (CPA) have been significantly boosted in terms of average power by moving from Titanium Sapphire amplification medium to Ytterbium based media. With Ytterbium, lasers delivering sub-picosecond pulses with average power of several tens to hundreds of Watts are now commonly available. Despite major progresses with the Yb technologies, the main drawback is their pulse duration, ranging from 200 femtoseconds (fs) to the picosecond (ps). For many applications, this is simply not short enough. Thus, there is a need for technologies capable of shortening the pulse duration of Yb laser systems to the femtosecond time scale.
The novel technology introduced by INRS researchers provides an efficient and robust solution to address this technological challenge. Using nonlinear propagation of 700fs pulses in a hollow core fiber (HCF) filled with a Raman active molecular gas, few-cycle pulses (10.8 fs) has been directly generated in the above self-focusing regime. While one might expect the pulses to break up into a mess of complex modes, a self-organization of the propagating pulses into spatiotemporally confined multimode multidimensional solitary states (MDSS) leads to strong nonlinear enhancement. The exhibition of these multimode features has huge potential to revolutionize high-energy laser technology. With the now-demonstrated capacity to directly generate energetic red-shifted pulses (compared to picosecond pump pulses) with few-cycle duration (compressed only with simple pieces of glass instead of expensive chirped mirrors), this technique can become an integral part of important applications such as laser-based material processing and for the generation of secondary sources from the THz to the X-ray spectral range. The target commercial price for the proposed technology will be in the range of $25,000, which is a small investment compared to the price of Yb CPA lasers (>$100,000). The market assessment will help to confirm the interest of Canadian and foreign companies for the tech transfer and the commercialization of the proposed technology.
近年来,通过从钛蓝宝石放大介质转向镱基介质,基于啁啾脉冲放大(CPA)的超快激光器的平均功率得到了显着提高。有了镱,现在可以普遍使用平均功率为几十到几百瓦的亚皮秒脉冲的激光器。尽管 Yb 技术取得了重大进展,但主要缺点是其脉冲持续时间,范围从 200 飞秒 (fs) 到皮秒 (ps)。对于许多应用程序来说,这还不够短。因此,需要能够将 Yb 激光系统的脉冲持续时间缩短至飞秒时间尺度的技术。
INRS 研究人员推出的新技术为应对这一技术挑战提供了高效而强大的解决方案。利用充满拉曼活性分子气体的空心光纤 (HCF) 中 700fs 脉冲的非线性传播,在上述自聚焦状态下直接生成少周期脉冲 (10.8 fs)。虽然人们可能期望脉冲分解成一堆复杂的模式,但传播脉冲自组织成时空限制的多模多维孤立态(MDSS)会导致强烈的非线性增强。这些多模特征的展现具有彻底改变高能激光技术的巨大潜力。目前,该技术已被证明能够直接生成周期持续时间短的高能红移脉冲(与皮秒泵浦脉冲相比)(仅使用简单的玻璃片而不是昂贵的啁啾镜进行压缩),因此该技术可以成为重要应用的一个组成部分,例如基于激光的材料加工以及从太赫兹到X射线光谱范围的二次源的生成。拟议技术的目标商业价格将在 25,000 美元范围内,与 Yb CPA 激光器的价格(>100,000 美元)相比,这是一笔很小的投资。市场评估将有助于确认加拿大和外国公司对技术转让和拟议技术商业化的兴趣。
