SMV-2022-31: He-Ne-I2 cells
Hrabina, Jan ; Holá, Miroslava ; Lazar, Josef ; Šarlejová, Tatiana ; Šlechtický, Stanislav
The contractual research was oriented towards the development of optical frequency references intended for the frequency stabilisation of ultra-compact laser sources. These optical references were based on absorption cells filled with ultra-pure absorption gases and they allow precise locking of the lasers with the methods of laser spectroscopy. The cells will serve as the references of optical frequencies in systems of primary length standards (633 nm wavelength).

Optical coatings for absorption cells
Oulehla, Jindřich ; Hrabina, Jan ; Holá, Miroslava ; Pokorný, Pavel ; Lazar, Josef
One of the key optical components used in laser stabilisation is an absorption cell filled with a gas medium. The optical windows of these cells are antireflection coated to minimise optical losses. During the production process, these coatings are subject to high temperatures and are in direct contact with the gas medium. In some special applications, there might be other factors, such as cosmic radiation, to consider. This contribution deals with the coatings’ resistance to these effects.
