Tremendous economic growth is expected in the upcoming years for infrared (IR) technologies in view of the fact that major scientific projects as well as industrial and medical applications require reliable light sources and detectors in this spectral range. The entire photonic industry is more and more dedicated to access these wavelengths with major foreign companies as well as a growing number of Canadian based companies. Over the next five years, through the strong financial contributions and commitments of our Canadian industrial partners O/E-Land Inc. and few-cycle Inc., and with the support of NSERC and PROMPT, we will work on emerging novel ultrafast (picosecond to femtosecond) laser technologies in the vicinity of 3 microns wavelengths, as well as to reach longer wavelengths using difference frequency generation (DFG). More specifically, with O/E-Land, we will use the promising amplification medium of dysprosium doped ZBLAN fiber with a gain ranging from 2.8 to 3.4 microns. With this gain medium, our goal is to emerge a fiber-based pulsed laser system that will have a dual-wavelength output and a tunable frequency difference, from which a compact, tunable, long wavelength infrared (LWIR) light source will be generated, which will be of high usability to end-users due to its flexible range of use. With few-cycle, we will exploit the Frequency domain Optical Parametric Amplification (FOPA) technique, to develop a high average power laser delivering high energy few-cycle pulses at 3 microns. This effort will capitalize on recent major investments from the Canada Foundation for Innovation in high average power Ytterbium laser systems. For our partner, this represents a unique opportunity to acquire knowhow and expertise within a spectral range that they have not yet addressed, but that bears major commercial opportunities due to the establishment of large scale ultrafast laser infrastructures around the world. Using the FOPA technology, we will also explore the generation of high-field ultrashort LWIR pulses, as well as a joint effort with O/E-Land to develop a compact and robust IR source using an economic picosecond laser.

鉴于主要的科学项目以及工业和医疗应用需要可靠的光源和探测器，预计在接下来的红外（IR）技术的几年中，预计经济增长将有可靠的光源和探测器。整个光子行业越来越致力于与主要的外国公司以及越来越多的加拿大公司访问这些波长。 在接下来的五年中，通过我们加拿大工业合作伙伴O/E-Land Inc.和Dire-Cycle Inc.的强大财务贡献和承诺，并在NSERC和PINST的支持下，我们将致力于新兴的Noveling Ultrafast（Picsocecond至fomtosecond）激光技术，在3微米的传播中，使用了3 microns Wearly的频率，并延长了差异（及其差异）。更具体地说，使用O/E-Land，我们将使用有前途的脱发ZBLAN纤维的有前途的扩增介质，增益范围为2.8至3.4微米。使用这种增益媒介，我们的目标是出现一个基于双波长的激光系统，该激光系统将具有双波长输出和可调的频率差，从中将产生紧凑，可调，长波长红外（LWIR）光源，这将是由于其灵活的使用范围而对最终用户提供的高可用性。 使用少数周期，我们将利用频域光学参数扩增（FOPA）技术，以开发出高平均功率激光器，在3微米处提供高能量脉冲。这项工作将利用加拿大高平均功率YTTERBIUM激光系统创新基金会的最新重大投资。对于我们的合作伙伴来说，这是一个独特的机会，可以在他们尚未解决的光谱范围内获取知识和专业知识，但是由于在世界范围内建立了大规模的超快激光基础设施，因此拥有主要的商业机会。使用FOPA技术，我们还将探索使用经济的Picsecond Laser与O/E-Land的共同努力，以及与O/E-Land的共同努力，与O/E-Land的共同努力一起开发紧凑而强大的IR来源。
