Nondegenerate optical Kerr effect in semiconductors
... The constant K was determined from the average degenerate 2PA coefficient of several semiconductors to be ~3100cmGW- 1 eV 5 1 2 , but varied by up to ~30% from one material to the next [9]. A value forK of ~4000 gives a better value for ZnSe and ZnS · as compared to the calculated value of 1940 cmGW ...
