摘要：

Experimental evaluation of non-linear susceptibility coefficient d22 for InSe, which is responsible for second harmonic generation in this material at 1.06 and 10.6 μm, is reported and the value compared with GaSe. At the CO2 laser frequency of oscillation, phase matching has been observed and a value of d22 almost equal to d15 for CdSe has been found. The InSe high transparency in the wavelength range 1.1-22 μm, the sizeable value of d22 and the possibility of reaching phase matching condition in the IR range make InSe a potential device for far IR frequency conversion. © 1979.
