    Further advancement of high-energy pulsed lasers requires a parallel development of appropriate optical components. Several different optical components, such as mirrors and antireflection-coated windows, which are essential for the design of HiLASE high average power lasers were tested. The following paper summarizes results on the measurements of laser-induced damage threshold of such components, and clearly shows their capabilities and limitations for such a demanding application.This work is co-financed by the European Regional Development Fund, the European Social Fund and the state budget of the Czech Republic (project HiLASE: CZ.1.05/2.1.00/01.0027, project DPSSLasers: CZ.1.07/2.3.00/20.0143, project Postdok: CZ.1.07/2.3.00/30.0057). This research was partially supported by the grant RVO 68407700.

    1 Introduction

    The laser-induced damage threshold (LIDT) is the highest quantity of laser radiation incident upon the optical component for which the extrapolated probability of damage is zero[1]. As a consequence, it is easy to understand why the LIDT is a key parameter for all optical components which will be used in design of any high-power laser systems. The importance of the LIDT of each optical component in such type of laser systems is reflected by the fact that the LIDT establishes the limits of maximum achievable energy of a whole laser system. Reliable and stable laser sources, desirable for both the academic and the industrial sector, require a careful testing and a development of involved optical components to meet certain quality criteria. In addition, the LIDT is also a limiting factor for the laser beam distribution system (LBDS), a system of optical components used to deliver such powerful laser pulses toward an area of scientific and industrial application.
