Four-photon spectroscopy of excitons in hexagonal zinc sulphide

Laser diagnostics of exciton states in ZnS crystal at 80 K, using third-order optical processes, is reported. Expressions of the effective nonlinear susceptibilities for the studied crystal configuration, are obtained. Longitudinal exciton of E = 3.8940 eV energy in hexagonal zinc sulphide is observ...

Description
Summary:Laser diagnostics of exciton states in ZnS crystal at 80 K, using third-order optical processes, is reported. Expressions of the effective nonlinear susceptibilities for the studied crystal configuration, are obtained. Longitudinal exciton of E = 3.8940 eV energy in hexagonal zinc sulphide is observed for the first time. An assignment to the 1s exciton of B series in ZnS, is made.
