Understanding the Basics
Although lasers range from quantum-dot to football-field size and utilize materials from gases to solids, the underlying operating principles are always the same. This article provides the basic information about how and why lasers work. When the laser was first demonstrated in 1960, it sparked a wave of public interest. Soon, however, many scientists and engineers dismissed the laser as “a solution without a problem.” Time has proved the critics very wrong. From communications...
