Optical Parametric Generation, Amplification, and Oscillation

Several areas of research, such as spectroscopy, semiconductor analysis, photochemistry, and remote sensing, have need of a tunable coherent source of high-power or high-energy radiation. Rugged solid state devices are desired to replace tunable dye lasers to avoid, among other things, the handling of toxic materials and requisite changing of dyes due to their continual photodegradation. In addition, a wider tuning range, especially into the near-and far-infrared, is needed.
