Methodology for the characterization of the laser rod shape by multi-wave interferometry
Matoušek, Ondřej; Kredba, Jan; Procháska, František
2020 - Czech
The developed methodology describes the method of the multi-wave interferometry with controlled phase changing and the way of its application for the characterization of laser rod, which allows measurement of the shape of the front surfaces, wedge, deformation of the passing wavefront and internal inhomogeneity in a single measuring cycle Vytvořená metodika popisuje metodu multi vlnové interferometrie s řízenou změnou fáze a způsob její aplikace pro charakterizaci laserových tyčí, která umožňuje měření tvaru čelních povrchů, klínu, deformace průchozí vlnoplochy a vnitřní nehomogenity v jediném měřícím cyklu.

Stability of an optical monitor for deposition of 42-layer interference bandpass filter 520-590 nm
Žídek, Karel
2018 - Czech
We report on stability of a deposition process of a complex system of thin layers. The layers were designed as a 42-layer bandpass interference filter. The layers of TiO2 and SiO2 were monitored both by the means of a crystal and an optical thickness monitor. We discuss the case when the design of the interference filter is continuously adapted according to the real thickness of the already deposited layers. V této zprávě popisujeme stabilitu depozice komplikovaných soustav tenkých vrstev, které byly navrženy jako interferenční filtr s pásmovou propustností. Jde o 42 vrstev TiO2 a SiO2, které jsou monitorovány jednak tzv. krystalovým a optickým monitorem tloušťky. Diskutujeme případ, kdy je návrh IF průběžně upravován podle reálné tloušťky deponovaných vrstev.
