Optical Performance Comparison of Argon-Ion and Solid-State Cyan Lasers

Edward H. Wahl, Bruce A. Richman, Chris W. Rella, Guido M. H. Knippels and Barbara A. Paldus

Recent advances in biotechnology have created a need for compact, efficient and reliable 488-nm cyan lasers, a trend which has hastened the development of technologies to replace air-cooled argon-ion lasers in biomedical instrumentation applications. more>>

Optical Slow Wave Structures

Andrea Melloni, Francesco Morichetti and Mario Martinelli

Nonlinear processes are enhanced in slow wave structures that consist of a cascade of directly coupled optical resonators. Although slow wave propagation has not yet been deployed at optical frequencies, new research could make slow wave structures the cornerstone of switches and other wideband devices for all-optical processing. more>>

Impressions of Kyrgyzstan

Akhlesh Lakhtakia

OSA’s International Council partially funded an 11-day trip to the Kyrgyz Republic by Akhlesh Lakhtakia, a professor of engineering science and mechanics at Pennsylvania State University. Lakhtakia toured the country, lecturing on sculptured thin films, observing the culture and sampling kabobs. more>>

Light Touch

The Phantom Laser

Stephen R. Wilk

In most cases, laser alignment is a delicate, time-consuming process. That’s why I was really annoyed when I found that an unstable resonator system I was working on had spontaneously “decided” to become a perfectly aligned stable resonator. The power concentration at the end mirror had become so great that it had blown the coating off the multilayer stack. more>>

An Optical Scientist Has the President's Ear

Tom Price

It sounds odd coming from the mouth of a presidential advisor, but John H. Marburger III insists he’s not much interested in government.What does interest him is science—optical science, to be precise. more>>
