THE Made by Laser, 1972
The caption for this image from Bell Laboratories in October 1972 reads: "This 'THE' is formed by machining a large number of discrete 'holes' in a thin coating of bismuth metal. Each hole is made by a single laser pulse. Such graphic information might one day be transmitted over telephone or high capacity digital channels."
