Laser processing systems enable us to precisely process different materials according to the requirements of individual applications through the ablation process. One of the optodynamic phenomena caused by the ablation process is the shock wave. Due to the high pressure of the shock wave, it can be detected by a laser deflection probe, where its detection can be used to monitor the ablation process. The laser deflection probe works according to the principle of the law of refraction, where the beam of the deflection probe is deflected by the high pressure of the shock wave. This increases the density of the medium through which it passes, causing a change in the refractive index which results in the refraction of light as the shock wave passes through the deflection probe. The aim of the master's thesis is to investigate and experimentally test a method of monitoring the ablation process based on the shock waves generated after each laser pulse. We designed the necessary experimental set-up based on a laser deflection probe and characterised it accordingly, which allows us to investigate the relationship between the effect of laser ablation and the response of the laser deflection probe in more detail.
