The Proactive View From Germany
As part of a joint presentation on Germany’s drive to keep pace in global, high-tech competition in research development and production, the Institute for Economic Research in Hamburg, Germany, suggests that the country must embrace an economic...

We Need to Curb Conflicts in Global High-Tech
There is remarkably little multinational cooperation for the development of new, commercially relevant technologies. There are regional efforts -- notably among the members of the European Union - but, even in Europe, national programs dominate...

Diode-Pumped Solid-State Lasers Find Their Place in the Lab
The $100 million-plus annual scientific laser market continues to be a prime area of opportunity and focus despite limited research and development expenditures in recent years. Historically dominated by gas, lamp-pumped solid-state and dye lasers,...

Lasers Control Molecular Motion
In quantum mechanics, interest has turned toward controlling, rather than explaining, atomic, molecular and electronic processes. The technology of coherent control employs light-induced interference to affect the dynamics of matter and assist in...

Lasers Offer Coherent Control of Material Behavior
The goals of laser control in chemistry include manipulation of collective and molecular properties. Femtosecond lasers have already helped study crystal lattices, and more extensive manipulations are expected because of advances in laser pulse...

Objective Measurements Improve Imaging Optics
Determining optical quality is no easy task because of the trade-offs in specifying imaging optics. For a quantitative assessment of optics, engineers turn to modulation transfer function measurements, which measure the frequency response of an...

Optical Fiber Reaches from Lab to Factory
The use of fiber optics in the laboratory has been steadily increasing for five years. Optical fiber devices can be used for temperature sensing, pressure sensing, pH measurements and material-specific sensing. However, the bulk of laboratory demand...
