In this work we embark on a short journey through the field of light and matter interaction with the focus on the optical damage and optical fatigue of materials. These two phenomena often limit the applicability of optical elements and inhibit techn

Often the limiting factor of modern high intensity light systems is optical damage threshold of the various components used. This limit is ever more tightening with increase in repetition rate as the multipulse optical damage threshold goes down with

Laser-induced damage threshold decreases when an optic is exposed to multiple laser pulses. In the femtosecond regime, the fatigue of dielectric materials is attributed to incubation of laser-induced lattice states. The goal of this study is to inves

The decrease of laser-induced damage threshold (LIDT) of optical materials when irradiated with multiple laser pulses is an important phenomenon commonly known as the optical fatigue effect. In case of pulsed femtosecond irradiation fatigue is usuall

So called “optical fatigue effect” of transparent optical materials is triggered by repetitive laser pulses. It first appears in form of gradual modification of optical properties of the element (change in refractive index or absorption) and even

The decrease of laser-induced damage threshold (LIDT) when exposed with high number of laser pulses is a well-known phenomenon in dielectrics. In the femtosecond regime this fatigue is usually attributed to the incubation of laser-induced lattice def

Efficient, diode-pumped high energy femtosecond laser systems around 1 μm based on Yb-gain media are readily commercially available. However, owing to the gain bandwidth limitations, the pulses generated in such lasers are substantially longer than

In order to correlate laser damaging fluence with the pertinent theoretical considerations, there were many attempts in the past to establish reliable damage predicting criterion. Such criterion then could be used to estimate laser fluence that trigg
