Lasers and Their Prospects

Lasers are indeed a phenomenal discovery. They help facilitate and shorten the space of time it takes to complete its work as opposed to the old method. Scientists have and are still discovering the multitude of ways in which they can be utilized. Lasers are, in simple language, generators of light. Discussed in this book are the components that make up lasers, the types of lasers and the advancement of lasers. They have begun from the simple generators of light, to radio receiving equipment, for transmitting signals for communication both on the Earth and in Space practically over any distance. They can even make radar observations of celestial bodies. In medical practices for certain surgeries and operations lasers are now widely used. They can find application in ranging and navigation, in biology, in chemistry and geophysics and countless others. Scientists use lasers to investigate various substances, for the study of the characteristic properties of atomic and molecular structures, for a better understanding of their interaction, for the determination of the biological structure of living cells. Lasers hold the greatest promise for diverse technical uses. They can find applications in ranging and navigation, in medicine and biology, in chemistry and geophysics. Our time is that of space travels. But before starting space journeys to other distant worlds men should make certain about the existence of extra-terrestrial civilizations. If such civilizations really exist somewhere in the Universe, then, quite probably, lasers will help us to get into communication with them. One of the more fascination proposals in this book, a translation from a work originally published in the Soviet Union, is a laser beam pipeline allowing the transmission of gases to the Moon. It is impossible to predict all the other fields in which lasers can and will actually be employed, but there can be no doubt that these wonderful devices have a great future.
