Laser damage resistance of coatings is determined by thin film materials and multilayer designs, all of which limit the overall performance of optical elements and all laser systems. Coatings that consist of high band-gap materials and are capable to

All-silica mirrors, formed by glancing angle deposition method were conditioned using laser radiation in order to increase the optical resistance. LIDT values reaches over 200 J/cm2 in ns regime at 355 nm wavelength.

Zero angle polarizers and achromatic waveplates were coated using anisotropic thin films. Multilayer approach with different orientations of optical axes for individual layers allowed for independent control of perpendicular polarization intensity an

Chirped mirrors with porous top layer (CMPTL) feature broadband dispersion control. In this work, CMPTL for broadband spectral range was designed and deposited. Additionally, sensitivity of CMPTL spectral parameters to humidity in air was investigate

The effectiveness of ultrashort pulse compression depends on the coatings group delay dispersion (GDD) characteristics in chirped mirror (CM)-based optical systems. Current porous-layer-based CMs with low GDD oscillations are limited to less than hal

In this work we present a new all-silica coating - polarizer, which is also capable to withstand high density of radiation. In order to demonstrate the versatility of presented approach, several coating designs have been modelled and two of them fabr

Optical components are the main parts in laser systems, which limit the total generated output power due to laser-induced damage. At nanosecond laser pulses materials experience thermal expansion, therefore optical coatings gain stress leading to bre

Optical components are the main parts in laser systems and also the limiting factor for high power laser. All-silica based optical components proved to have extremely high laser induced damage threshold and were already tested on standard glass subst

Several fundamental restrictions limit the implementation of microlasers in high power systems, low resistivity of coatings and compactness of elements, especially if control of polarization is necessary. Thin-film-based coatings with extremely high
