___ focus (intense concentration) (5)

Ross

I believe the answer is:

laser

(Other definitions for laser that I've seen before include "Beam (used in surgery)" , "Device that generates an intense ray of light" , "Device producing an intense beam of light or radiation" , "Device for concentrating light" , "light-intensifier" .)

I've seen this clue in the USA Today.
