Written by Allan Lytel. A Thomas Sams Photofact publication, first edition, first printing 1963. This book explains the uses of Lasers and Masers and their applications. Masers in their fundamental action are completely different then vacuum tubes or transistors, while electronics abound with many new techniques and applications, most of these are modifications of pre-existing knowledge and do not represent revolutionary ideas. The Maser is an entirely new concept. Noise-Free amplifiers and ultra-stable signal sources are just two Maser applications. A special type of Maser, called the Laser, is a light amplifier and source of coherent light; it is a spectacular by product and the first ever produced by man. |
