Nick Karayianis, 57, a theoretical physicist who was a former branch chief of the Army Materiel Command's Harry Diamond Laboratory, died of cancer Feb. 25 at his home in Rockville.

Dr. Karayianis, who became an authority on laser technology, joined the lab in 1954. He served as chief of its applied physics branch from 1978 to 1983. After that, he worked on projects involving radar and signal processes before retiring in June 1988.

He was the recipient of a 1971 Army research and development achievement award and received another Army achievement award in 1987. He also was presented the Army's 1986 Wilbur S. Hinman Award.

He was the author of 57 technical articles and 54 government reports and held more than a score of patents. Dr. Karayianis was a native of Washington and graduate of Roosevelt High School. He received bachelor's and master's degrees in physics from George Washington University and a doctorate in theoretical physics from Indiana University. He began his government career in 1952 at National Bureau of Standards, where he worked two years.

In his youth, he had played softball. A golfer, he had been a member of the Montgomery, Bethesda and Norbeck country clubs. In 1957, he had been supreme president of the Sons of Pericles, a group that is part of AHEPA, a Greek American organization.

Survivors include his wife of 27 years, the former Maria Buas, and two sons, George and Dean, all of Rockville, and a brother, Konstantinos (Dino), of Washington.
