Abstract

Two problems concerning the nonlinear optical properties of tellurium could never be solved satisfactorily: 1. The values of the nonlinear optical coefficient d11 of tellurium measured by different authors by second harmonic generation (SHG) of CO2 laser light scatter enormously /l/. 2. Even if one of the lower du values is used in the calculation, it should be possible to build a CO2 laser pumped parametric oscillator on the basis of tellurium /1/. But all attempts, e.g. /2/, to detect parametric generation (PG) in tellurium failed.
