“…In case of damage, the scattering signal is increased and irradiation is stopped. Software based on the programming package LabWIeW was used in order to control the measurement procedure: positioning of experimental sample in X and Y directions, attenuation of laser pulse energy, shutter, automation of damage detection and statistical result analysis [12]. The main parameters are presented in Table 2.…”

The nonlinear lBO (liB 3 O 5 ) crystal is widely used in many Nd : YAG, Yb : KGW and Nd : YlF lasers in order to generate higher optical harmonics. However, the most limiting factor in such applications is the optical resistance of their coated surfaces described by the so-called laser Induced Damage Threshold (lIDT) parameter. In this work we investigate the "fatigue" (multi-pulse) behaviour of lIDTs in lBO crystals coated with different types of (single AR@355 nm and triple AR@355+532+1064 nm wavelength) anti-reflective coatings while optimising the refractive index designs and selecting appropriate sub-layer materials. All the coatings were produced of different oxide materials (ZrO 2 , Al 2 O 3 , SiO 2 ) and ZrO 2 -SiO 2 mixtures by using the ion beam sputtering (IBS) deposition technique. The optical damage resistance of both fixed and transient refractive index coatings is of special interest. Besides the spectral properties, the resistance to laser irradiation is characterised at the wavelength of 355 nm with laser pulses of nanosecond duration. The conclusions are drawn about the AR coated lBO with the most successful designs by the means of optical resistance.

“…As a consequence, many detection methods have been reported in the literature, each one trying to give the most accurate threshold of the laser-induced damage occurrence. These methods include scattering (dark field imaging or scattering measurement of a probe beam), imaging, plasma detection, spectrophotometry, photoacoustic effect, reflectivity or transmittivity measurements [2][3][4][5][6][7][8][9][10][11]. Visual inspection under Nomarski (DIC) microscope is often found to be the most reliable and sensitive technique.…”

Laser-induced damage is defined as any permanent laser-induced change in the characteristics of a sample. This change can be observed by many different inspection techniques, with different sensitivity, depending on the intended objectives and available techniques. The damage threshold definition and measurement are therefore very subjective and related to the detection method. The choice and implementation of a damage test system is then a critical issue on any experiment. In this work we present some implementation of detection techniques for laser damage metrology in the sub-picosecond regime. Different damage testing methods that have been applied will be discussed in view of their potential applications for testing functional optical components or to study physical process in the femtosecond regime, particularly the role of defects: optical microscopy, phase microscopy and time-resolved microscopy.

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.
