Nonlinear Optics Using Atomic Coherence Effects
Nonlinear optical mixing of existing laser frequencies to access portions of the spectrum where lasing action is not easily obtainable is common practice today. Various techniques, including important new ones like quasi-phasematch¬ing in tailored nonlinear-media are aimed at efficient generation in the region of the spectrum from just under 200 nm in the ultraviolet to about a few microns in the infrared.
