LASER
1. The laser has become a multipurpose tool. It has caused a real revolution in technology and in the nature of productive labour.
2. The laser can cure diseases. It has become indispensable as a means of space communication. Its beam produces a sharp picture on the TV screen. Moreover, it can increase the size of the TV screen to that of a modern cinema. The laser cuts steel, pierces hard alloys and diamonds and drills holes through them a few microns in diameter.
3. Nevertheless, the laser no doubt has innumerable other applications which, we are still to discover.
4. Let us begin with optical methods of data processing. Technological progress calls for ever more efficient electronic computers. Multipurpose computers capable of performing more than ten million operations per second have already been designed and built. Laser devices will apparently make it possible to build extremely fast computer elements capable of doing up to a thousand million operations a second.
5. Today the enterprises are producing a number of machine tools and automatic devices intended for production lines. The machine tools for working jewel bearings for the watch industry and diamond files for wire drawing are now used on a wide scale. These machine tools bring a substantial economic effect. Machine tools employing carbon dioxide lasers for cutting quartz and glass pipes and for crystal and glass pipes and for crystal and glass engraving are being introduced into industry. Lasers have found an application in the printing industry.
