One Boy’s Auroral Expedition
Take a high school student with a fascination for the sciences, a yen for travel and some sophisticated equipment on loan from a professional photographer. Transport to Iceland, one of the best sites for viewing the aurora borealis.

The auto industry has long been driven by demands for better fuel economy and lower emissions. In Europe, these forces have led to the renaissance of the diesel engine. The latest generation of passenger car diesels is clean, efficient and powerful. These improvements have been enabled in part by advances in optical metrology.
by Thomas J. DunnThe Telescopes of Seventeenth-Century Italy
The seventeenth century was an important period of development for optical instruments. In 1600, the field was in its infancy. Fewer than 50 years later, a handful of inventors had created devices that were as perfectly optimized as available technologies would allow.
by Giuseppe MolesiniNonlinear Optical Spectroscopy and Imaging of Structural Proteins in Living Tissues
Traditional nonlinear optical tools, such as second harmonic generation, third harmonic generation and coherent anti-Stokes Raman spectroscopy, are being used to image the morphology and organization of protein arrays in live cells and tissues.
by Paul Campagnola and William A. MohlerA Quasiperiodic Approach to Ultrashort Pulses
To optically control atomic and molecular processes, it must be possible to shape the optical waveform with a high level of precision. This involves maximizing the number of phase-adjustable frequencies. The authors demonstrate a technique to multiplicatively increase the number of generated frequencies through the use of modulators in series.

Early Meetings of the International Commission on Optics
Representatives of the international optics community joined together in the wake of World War II to further the study of optics. OPN Contributing Editor John N. Howard traces the historical trends that led, in 1947, to the formation of the International Commission for Optics.

OFC 2003: The Technology Marches On
Despite war and a sluggish economy, approximately 15,000 people attended the 2003 Optical Fiber Communication Conference & Exposition (OFC) in Atlanta, Ga. This was down from 32,000 in 2002. Still, the meeting was vibrant testimony to the fact that progress on the fiber optics technology front continues.
