Lens problems scupper 157nm
Moore’s Law is still holding true, with the insatiable demand for ever-faster semiconductor chips driving the development of lithography tools that operate at increasingly short
wavelengths.
Chinese star eyes Europe
China's largest maker of industrial lasers is searching for international partners to grow its business. Oliver Graydon met Chutian Laser chairman Sun Wen at LASER 2003.
Thin disk sources get powered up
After successfully entering the ophthalmology market, the next challenge for thin-disk lasers is materials processing. Trumpf and Rofin-Sinar are backing the technology with multikilowatt-scale systems, as Michael Hatcher reports.
Gratings and etalons ease wavelength tests
Knowing the precise wavelength or spectral content of your source can be crucial in many applications. Jacqueline Hewett investigates the technology behind wavelength meters and handheld spectrometers, two instruments that are designed for this task.
