Multifunction setup for the measurement of resonant optical responses of semiconductor structures in the visible and IR spectral ranges with subpicosecond time resolution

A multifunction setup for coherent optical spectroscopy with excitation of semiconductor structures in a wavelength interval of 750–1800 nm and a time resolution of about 100 fs is presented. Minor adjustments are needed for the measurements of photoluminescence kinetics, photon echo, and four-wave mixing under excitation of samples using time-correlated series of femtosecond laser pulses. Results of optical experiments are presented.
