During the last few years fiber lasers have become the hottest topic in material processing applications. In macromachining applications they have been able to take market share from conventional lamp pumped YAG-lasers while also enabling totally new applications that so far have not been in the reach of conventional laser tools. Micro manufacturing processes are the fastest growing applications for lasers due to the dynamic consumer electronics mar...$28.00

There is no doubt that we need an energy cycle free of fossil fuels that otherwise emit greenhouse gases causing global warming. Although solar energy is the ultimate renewable energy source, sunlight is available only in the clear daytime and hence it cannot be an alternative to thermal power stations unless effective and large power storage systems a...$28.00

Presented at ICALEO 2007
Laser micromachining provides a new method of producing parts in a wide range of materials directly from CAD data. Particularly, in laser milling technology the material is removed by a laser beam through the layer by layer ablation mechanism.
The aim of this paper was to determine the process capability of the laser micro-milling process, optimising the surface finish and at the same time keeping an high mater...$28.00

Liquid Crystal Displays (LCDs) represent the most widely manufactured form of Flat Panel Display (FPD) in the world today. This market is extremely price sensitive and so competition is fierce. In an attempt to reduce costs, manufacturers are always interested in new technology to gain a lead on their competition. In recent years laser use has been increasing in the manufacture of FPDs most nota...$28.00

Characteristics of emitted particles as well as EUV emissions from a laser-produced tin plasma using a colloidal tin dioxide nano-particle jet target were investigated as a possible EUV lithography light source. By using double nano-second YAG laser pulses with an optimum delay of 100 ns, the EUV conversion efficiency of 1.2% at 13.5 nm was observed. The energy and streng...$28.00

Drilling of small diameter holes (< 0.2 mm) in thick (> 2 mm) industrial materials require high peak power lasers of single-mode beam quality and at a wavelength that is absorbed by the material. The number of holes drilled per second or the processing throughput increases linearly with the laser average power. In this paper, we will present the results of a rotary disk laser, which is a completely new type of pulsed solid state laser system that produces the ideal combination of high peak power, high average pow...$28.00
