Abstract:
The aim of this study was to assess the surface and the substrate/glass ionomer cement (GIC) interface after Er:YAG laser irradiation by means of scanning electron microcopy. Material and methods: Thirty human third molars were selected and had their roots removed. Crowns were sectioned to obtain discs that were randomly assigned to three groups according to the surface pretreatment: 40% polyacrylic acid (control); Er:YAG laser irradiation (80mJ/2Hz) or Er:YAG laser followed by 40% polyacrylic acid. Two discs of each group were put aside to the surface analysis and the others were bisected. On

Abstract:
We present the design of a free-electron laser (FEL) doubler suitable for the simultaneous operation of two FEL lines, in either self-amplified spontaneous emission or externally seeded configuration. The doubler relies on the physical selection of two longitudinal portions (beamlets) of a single electron bunch at a low energy and on their spatial separation at high energy. Since the two beamlets are naturally synchronized, FEL pump–FEL probe experiments are enabled when the two photon pulses are sent to the same experimental station. The proposed solution offers improved flexibility of

Focused ion beam (FIB) technology is one of the most widely used methods for fabricating crosssectional analysis specimens because of its high precision and characteristics that minimize the occurrence of defects. Demand for large cross-sectional area analysis is increasing to improve product reliability in various industries, but is limited by the low milling speed of FIB. Other potential techniques such as Ar ion milling and plasma FIB have been adopted, but low milling speed for large areas still remains a problem.

Abstract:
The thin-film active quasi-waveguide (Fig. 1) is a system which consists of a thin (up to several dozen wavelengths) active layer inserted between two passive dielectric media with refractive indexes higher than those of the active medium. Therefore this system has only leaky modes. In the active quasi-waveguide the role of mirrors of the ordinary resonator is carried out by the boundaries of the active layer with the coefficient of reflection determined by Fresnel's formulae. The order of interference determines the modes of quasi-waveguide radiation analogous to transverse modes of an ordina

Abstract:
Laser beam welding (LBW) has become standard in many high-production and critical applications where the return on investment can be quickly realized due to the process' inherent efficiency in terms of weld penetration and travel speed. Also, some promising work has been done internationally related to the use of hybrid laser/arc welding (HLAW) for some applications (primarily shipbuilding), so this process variation was also included in the study. However, virtually all of the current LBW or HLAW applications are considered 'factory' applications, and therefore do not represent the logistical
