The applicability of lasers to the logic, memory, inputoutput, and data transmission linkages portions of computers are analyzed qualitatively. The more promising potential applications are considered to lie in the memory, interconnection, and input-output areas, and the least promising in the fast logic area. Coherent optical data preprocessing is cited as an example of an already clearly useful laser application.
