All About Lasers (with projects)


AMAZON multi-meters discounts AMAZON oscilloscope discounts

From phone lines and videodiscs to surgical procedures and optical computing—the laser is one of the most important inventions to come along during this half of the 20th Century. This guide gives you this opportunity to investigate, first hand, a relatively new and evolving science. With this guide you can create and experiment with simple to advanced-level lasers that have real, practical applications!

The laser-based projects presented here are geared toward the garage-shop tinkerer on a limited budget. Spanning a wide range of disciplines, the projects vary from experimenting with laser optics and constructing a laser optical bench to using lasers for light shows, gunnery practice, even beginning and advanced holography. High-quality laser art illustrates instructions and detailed project parts list puts all the information you need to get started right at your fingertips! There is even. On electronic construction techniques ... how to laser components ... when to buy surplus or new ... and how to get what you really want! Many of the topics covered are ideal for science fair projects as well as teaching tools for any one interested in learning how lasers work and what they can do.
