Laser Crystals for Extreme Optics – CLOE

Submission summary

Cristal Laser has always had a strong philosophy of continuous improvement of its growth processes and products manufacturing. Today, Cristal Laser is especially focusing on strengthening the quality of its nonlinear crystals to offer both robust and reliable solutions over time for high-power ultraviolet lasers. Indeed, the high-power UV lasers market is currently booming with applications range from semiconductors to space. And we witness a real technological race for higher power that always demands components of higher performance. Therefore, it is important for Cristal Laser to offer a technically suitable product for UV lasers that would give the company a significant competitive advantage on the world stage in the years to come.
Here’s one example of higher requirements in UV laser field :
the European Space Agency (ESA) is starting a new Aeolus follow-on program whose goal is to multiply by 3 the power of the UV laser and by 7 the lifetime of the 355nm laser within 5 years. Such a technological breakthrough will inevitably require the development of technical solutions for UV-generating crystals.
Cristal Laser also notices these higher technical requirements in its industrial partners : Airbus, Amplitude, Thales, Trumpf, or Nikon
As for the CEA, it offers a unique platform with a wide range of lasers, from the ultra-short pulses (20fs) to the continuous regime, from the near infrared (1µm) to the medium ultraviolet (200nm). The CEA will therefore be able to provide its industrial partner with extensive opportunities for trials and tests that will enable to determine which are the components key parameters depending on the laser type, and especially in the UV. On the other hand, CEA researchers will also provide Cristal Laser with a deep theoretical scientific support in laser-matter interaction so that it can orient its developments, improve its crystal growth processes, and refine the important parameters of the components that would be integrated into its customers' lasers.
The instrumentation implemented at the CEA will also serve as a reference for the jointly developed benches that will later be installed at the industrial partner’ site for production monitoring or R&D. At the same time, the CEA will also renew part of its instrumentation and develop new benches that will allow an in-depth study of the processes of creation and relaxation of defects induced by ultraviolet laser at different time scales in dielectrics, a very rich scientific theme that is now booming.
