This paper represents an attempt to illustrate BTL efforts in technological applications of lasers. Included are brief accounts of the BTL contributions to cw lasers in the visible and to light deflectors, which have provided the basis for many applications. A description is given of the work on holography and optical memories, of the primary pattern generator, the remote blackboard system, and of work on micrographics.
