Abstract: The nonlinear optical properties of multilayer heterostructures based on zinc chalcogenides are studied. Rapid variations in the reflection and transmission of samples excited by ultrashort laser pulses are demonstrated. The characteristic relaxation times of the induced nonlinearity are 2 — 5 ps and are almost independent within the experimental error on the excitation energy and temperature of a sample.
