A facsimile system using room-temperature injection-laser scanning
This paper reports the first use of CW room-temperature injection lasers in a scanning facsimile system. The document reader can resolve about 2000 spots in each horizontal line of its raster scan, which is close to the performance attained using an He-Ne gas laser. The results obtained thus suggest that these small, efficient lasers can replace gas lasers in many applications.
