is often attributed to greater measurement uncertainties while in the ultraviolet. Specifics of this uncertainty

Hygroscopic Character: BaF�?absorbs humidity, which might degrade its optical and structural Houses. Protecting coatings or storage in dry environments are required to handle this problem.
Very low-Electrical power irradiation only brings about enlargement and deformation from the window, nevertheless the remarkably absorbent electrode discharging particles by using a diameter of 0.one∼one µm strongly absorb the laser. Robust community warmth is caused throughout the melting and gasification from the particles, which effortlessly causes ablation and cracks. The damaged region is proportional on the particle measurement, as well as the ruined rate is proportional to the typical electrical power density at a high repetition frequency. High energy density along with the defects with large absorptivity, the electrode discharging particles, and the heat accumulation outcome, are the most crucial components for The 2 short-expression injury, respectively.

φ, deg: The third signifies the azimuthal angle φ in levels. This angle specifies the orientation of your crystal axis in the airplane perpendicular for the propagation way.
The CaF2 window would be the laser exit in the DUV lithography equipment and also its sealing part. Bearing the irradiation, significant force, and discharging pollutants, the window is straightforward to wreck and right deteriorate the functionality and reliability from the laser. In this paper, considering the effects of the above aspects, two typical brief-time period damages towards the CaF2 window - substantial Electricity induced destruction and pollutant-induced damage are analyzed quantitatively. Working with an experimental structure, theoretical calculation, characterization analysis, and numerical simulation, we found that the damage induced by substantial-Power irradiation is dominated by defect propagation with the initial stage. Within the later on stage, it really is dominated by warmth and thermal anxiety with thermal melting and evenly dispersed microcracks of one∼10 µm in dimensions.
