Abstract:

In the research on nonlinear crystals and processes for frequency mixing in the infrared there has been progress along two fronts. The authors have produced tunable infrared from 11 micrometers to 23 micrometers by mixing the output from two ruby-pumped dye lasers in proustite. Analysis of the output power verses wavelength showed that beam convergence at the nonlinear crystal can be responsible for a substantial reduction in output from that which one would expect were the crystal at the beam waste. This effect is studied quantitatively and an excellent agreement is found between theory and experiment. It is shown that there are applications where randomly twinned crystals could meet specific needs for crystals to be used in nonlinear mixing processes. The authors have made a preliminary theoretical investigation of the effects of crystal absorption and twin spacing on the power production from a randomly twinned crystal. The authors have also found the probability distribution function for the power produced by a randomly twinned crystal.
