Intracavity generation of coherent optical radiation by optical mixing.

摘要

An efficient, compact source of coherent radiation in the infrared, visible and ultraviolet portion of the spectrum which is capable of modulation rates over the range from 0 Hz to in excess of 1 GHz. The radiation is produced by optical mixing within the optical cavity of a laser by introducing input radiation into the optical cavity where: (a) the cavity is that of a diode-pumped solid state laser, and/or (b) input radiation is provided by a solid state device selected from the group consisting of laser diodes, laser diode arrays and diode-pumped solid state lasers.
