Note
The advances made by solid-state lasers are comparable in many ways to those made by transistors forty years ago. Of major practical interest are the advances made in high efficiency, red-orange diode lasers which are relatively inexpensive, and compact green, diode-pumped, frequency-doubled lasers. Examples of some of the systems that have recently been demonstrated will be presented along with an overview of some of the solid-state, laser-based systems presently under development.
