Apparatus for the Efficient Wavelength Conversion of Laser Radiation.
Abstract
An apparatus for generating coherent radiation at a desired frequency is disclosed. In a preferred embodiment the apparatus comprises: an injection-locked semiconductor diode structure having a large active area for emitting a diffraction-limited beam at a preselected frequency; optics for focusing the diffraction-limited beam into a focused beam; a nonlinear crystal responsive to the focused beam for producing a beam of laser power which includes an output beam at a desired harmonic of the preselected frequency; and a device for passing the output beam in a given direction. In a modification of the preferred embodiment, the output of the injection-locked semiconductor diode structure is mixed with an emission from a laser source in the nonlinear crystal to produce a desired sum or difference frequency. Keywords: Potassium nitrate; Injection locked diode lasers; Semiconductor laser; Gallium aluminum arsenides; Frequency doubling; Second harmonic generation; Patent application. (AW)
