项目摘要

This NSERC-RTI application is for the repair of my group's femtosecond (fs) laser system. My team has dealt with three major laser failures in the last two years: one in mid 2017, one in late 2017, and the last one in winter 2019. The first and third failures were related to damage of the laser medium in the oscillator cavity while the second one involved damage of the laser crystal within the laser amplifier; supposedly triggered by the former. For each of these failures, we were able to bring the system back to operation by displacing the damaged crystals in order to obtain fresh spots, procedures that were performed with remote assistance from the laser company owing to our expertise in laser physics and the lack of funds to pay for such a repair. The laser oscillator continues to degrade as evidenced by the slow and constant decrease of power stability measured over the last six months. The unit must be sent to the factory. The repair will involve the replacement of the laser oscillator by a newly developed unit with a higher damage threshold and changing the amplifying crystals and the gratings in the stretcher/compressor to improve the transverse beam quality.******Since this funding request is for the repair of a very costly and specialized fs-laser unit that energizes custom-built instruments, there are no other more cost-effective alternatives or availability of similar equipment in the vicinity. The aforementioned laser failures already affected the research productivity of my team multiple times. There is an immediate need to repair this equipment since a permanent breakdown will impede the completion of MSc and PhD theses.
此NSERC-RTI应用程序用于修复我的团队的飞秒(fs)激光系统。我的团队在过去两年中处理了三次主要的激光故障:一次在2017年年中,一次在2017年底,最后一次在2019年冬季。第一次和第三次故障与振荡器腔中的激光介质损坏有关,而第二次故障涉及激光放大器内的激光晶体损坏;据推测是由前者引发的。对于每一个故障,我们都能够通过更换损坏的晶体来使系统恢复运行,以获得新的点,由于我们在激光物理方面的专业知识和缺乏资金来支付这种维修费用,激光公司在远程协助下执行了这些程序。激光振荡器继续退化,这可以从过去六个月测量的功率稳定性的缓慢和持续下降中得到证明。该装置必须送到工厂。修理工作将包括用新研制的损坏阈值更高的装置更换激光振荡器,并更换放大晶体和展宽器/压缩器中的光栅,以改善横向光束质量。由于这一资金申请是为了维修一个非常昂贵的专用fs激光装置,该装置为定制仪器提供能量,因此附近没有其他更具成本效益的替代方案或类似设备。前面提到的激光故障已经多次影响了我团队的研究效率。有一个迫切需要修理这台设备,因为永久故障将阻碍硕士和博士论文的完成。
