Theoretical and experimental study of high efficiency frequency tripling using large-aperture laser beam
On the base of three-wave interaction equations, the dependences of the maximum attainable tripling efficiency on the energy ratio of the fundamental wave to the second harmonic wave, crystal length, power density, input beam divergence and match-type are given. The experimental results of frequency tripling are in agreement with theoretical calculations. With type-II KDP used in tripling, energy conversion efficiency as high as 43% has been obtained for moderate power levels.
