But his research on semiconductor lasers was carried on, and this work on developing widely tuneable lasers for optical communications systems continues.

Soon afterward, other laboratories with accelerators started developing such lasers.

More recently, he worked to develop free-electron lasers as power sources in high-frequency bands.

The race was on to develop lasers for special uses-especially lasers of higher power.

Mr. Nixon instructed his negotiators to protect the right of the United States to develop such lasers but to ban deployment.

Santur Corporation was founded in November 2000 to develop and commercialize tunable lasers for fiber optic telecommunications.

Last year, the International Atomic Energy Agency revealed that Iran had worked in secret for 12 years to develop lasers for purifying uranium.

We are now developing high-energy pulsed lasers and particle beam weapons systems which operate at the speed of light.

In addition to designing arms, the laboratory has developed powerful lasers for trying to harness nuclear fusion for energy production.

In contrast, American researchers have developed lasers that only pulse on and off quickly for short periods of time.
