Abstract

Internal SHG efficiencies of 24% with signal strengths of 14 kW at 6.4 µm have been obtained by pumping tellurium with the 12.8 µm output from an optically pumped NH₃ laser. The effects of free carriers generated by two photon absorption are shown to be insignificant at this operating wavelength and a value for the non-linear coefficient of d₁₁ = 0.734 x 10^-5 e.s.u. was determined. © 1977.
