Popis:	Large, crack-free single crystals of AgGaTe 2 were grown for the first time using the horizontal gradient freeze technique. As-grown samples were transparent from 1.2 μm to beyond 16 μm (the spectrometer limit): they exhibited near-theoretical transmission at long wavelengths, but in the near-infrared transmission was limited by scattering from second-phase precipitates (much like AgGaSe 2 and AgGaS 2 ). Dilatometer measurements on oriented single crystal revealed severely anisotropic thermal expansion similar in sign and magnitude to that of the sulfide and selenide analogs. Preliminary refractive index data suggests that the birefringence of AgGaTe 2 may be slightly too small for phase-matched frequency conversion, but additional measurements over a broader wavelength range are required to refine the Sellmeier fits.
