To study the effects of laser fluence (laser energy density), scanning line spacing and ablation depth on the efficiency of a femtosecond laser for three-dimensional ablation of enamel and dentin. A ...

We investigated the effect of femtosecond (fs) laser ablation of enamel and dentin for different pulse wavelengths: infrared (1030 nm), green (515 nm), and ultra-violet (343 nm) and for different ...

Gigahertz femtosecond lasers are suited to enhance and regulate laser machining quality to engineer the physicochemical properties of materials. Materials scientists seek to understand the ...

A possible alternative to active debris removal (ADR) by laser is ablative propulsion by a remotely transmitted electron beam (e-beam). The e-beam ablation has been widely used in industries, and it ...

The demand for consistently high electrical performance in the power discrete semiconductor market has driven component developers to continuously enhance ...

An elemental examination of an item discovered during an inquiry might provide important information about its origin and history. However, since the item itself may need to be produced as evidence, ...
