Abstract:

A tunable source of narrow line radiation in the 2-6 micrometer band and, to a lesser extent, the 8-12 micrometer band would be useful in several military applications. Only recently have nonlinear optical materials become available to permit construction of optical parametric oscillators OPOs and mixers operating at these wavelengths. In this report, a review of the progress in wavelength coverage and output of OPOs and mixers is given, the theoretical performance of eleven nonlinear materials is discussed in detail, and as an example, the materials are compared for use in operating a singly resonant OPO in the 3-6 micrometer band. For this application, the outstanding materials are HgS pumped at 1.06 micrometers and ZnGeP2 pumped at 2.1 micrometers. Other material performances discussed are Ag3AsS3 Proustite, AgGaS2, AgGaSe2, Ag3SbS3, CdGeAs2, CdSe, LiIO3, LiNbO3 and Tl3AsSe3. Refractive index data on the nonlinear materials and details of the FORTRAN computer program used in the calculations are included.
