Chip Makers Weigh Benefits and Costs of Laser Marking Systems
In the fledgling days of the semiconductor industry, chip makers encoded serial numbers and dates on integrated circuit packages using conventional pad printed or ink-jet techniques. These methods offered users a high-contrast mark at a relatively affordable cost, but they also resulted in fumes, occasional smudging and the tedious task of refilling vast ink reservoirs. As incidents of...

Scientists Propose Design Strategies for Two-Photon Absorption
The principle behind two-photon-excited fluorescence microscopy is simple: In the presence of laser pulses, molecules simultaneously can absorb two or more photons at longer wavelengths with the same effect as absorbing one photon at a much shorter wavelength. Unfortunately for science, most known organic molecules have a relatively small photon absorption cross section, and the criteria for...
