Summary:Title screen
The diagnostic complex is designed to study the dynamic phenomena that occur in the interaction zone between a laser pulse and refractory oxides such as Nd:Y2O3, Fe2O3, ZnSe, and TiO2. This complex includes a compact brightness amplifier that utilizes copper bromide vapors, an optical objective, high-speed cameras (AOS Q-PRI and MegaSpeed-130MK), a digital synchronization system, a 1070 nm ytterbium fiber laser (LS-07N), a focusing lens, a quartz plate, a neutral density filter set, a pin photodiode (SFN2500FA), and a coaxial photocell (FEK-22). The active imaging system has a temporal resolution of 45 µs. Due to the intense glow of the laser torch resulting from the laser pulse impact on the target, it is not possible to capture images of the interaction zone and the evaporation process using passive filters. However, this issue is resolved by using the small-sized brightness amplifier (with dimensions of l = 38 cm, d = 1.5, V = 67 cm3), which allows for imaging of the droplets formed during the laser torch's presence. Additionally, the surface of the target in the interaction zone is also captured. The characteristics of the melt and the formation of large droplets during the laser pulse impact on the target are determined through this setup.
