SMV-2023-36: Wuhan Space
Hrabina, Jan ; Holá, Miroslava ; Oulehla, Jindřich ; Pokorný, Pavel ; Lazar, Josef ; Šarlejová, Tatiana ; Šlechtický, Stanislav
The contractual research was oriented towards the development of optical frequency reference intended for the frequency stabilisation of ultra-compact semiconductor laser sources. This optical reference is based on an absorption cell filled with ultra-pure absorption gases, and it allows precise locking of the lasers with laser spectroscopy methods. The cell will serve as a reference of optical frequencies in systems of laser standards (532-633 nm wavelengths).

DESIGN, DEPOSITON TECHNOLOGY AND CHARACTERIZATION OF THIN OPTICAL COATINGS FOR SPECIAL APPLICATIONS
Oulehla, Jindřich ; Kozák,, Martin (referee) ; Žídek,, Karel (referee) ; Sobola, Dinara (advisor)
The physical phenomena resulting from thin film optics have been known for several centuries. The oldest discovery which can be considered as modern day thin film optics is what is now called the Newton rings. The explanation of this phenomenon is quite simple, it is the interference of light on a thin film. However in the time of its discovery, due to the level of knowledge of optics, its explanation wasn’t possible for the next hundred and fifty years. The works of Augustin Jean Fresnel have been particularly important for the field of optics. He combined the results Young’s double slit experiment with Huygens’ ideas of light propagation into one theory – the theory of diffraction. The Frenel’s laws which govern the propagation of amplitude and phase of light reflected or transmitted over a boundary are essential. These laws along with the discoveries of his contemporaries (i.e. Siméon Denis Poisson) and followers (especially James Clerk Maxwell) are the foundations of thin film optics. Optical thin film technology went through rapid development in the 1930’s. Even though the principles of sputtering come from approx. half of the nineteenth century and the principles of vacuum evaporation come from the turn of the nineteenth century, these techniques were not considered useful production techniques especially because of the lack of usable pumping systems. It was the research in the area of diffusion pumps (and oils) in the 1930’s which made these techniques useful. Since then there has been a great technological development of these techniques, particularly towards the end of the last century. During the same period new requirements for the optical thin film properties have appeared. Not only were they required to perform well in the area of reflectance and transmittance but also to be able to withstand high intensity laser radiation. There is still a wide range of scientific and technological opportunities in the field of optical thin film production not only in the form of finding new materials or novel coating techniques but also in the usage of standardized technology for special and unique applications.
SMV-2022-62: Antireflection of sapphire windows between water/air for visible spectrum of light
Pokorný, Pavel ; Oulehla, Jindřich
Design and deposition of antireflective multilayers for near-perpendicular incidence of visible light on sapphire windows between air and water.
SMV-2022-37: Interferometers for coordinate measurement
Holá, Miroslava ; Hrabina, Jan ; Oulehla, Jindřich ; Pokorný, Pavel ; Lazar, Josef ; Šarlejová, Tatiana ; Šlechtický, Stanislav ; Humeňanská, Jana
The contract research was focused on the development of multi-axis measuring systems using the most accurate method of measurement based on the principle of laser radiation interference. The basic reference is a laser source with a wavelength of 633 nm. Measuring systems are intended for devices requiring measurement accuracy in the order of nanometers.
