The paper describes the design and performance of a double-beam pulse spectrometer used for measuring, in the real time, changes in transient absorption, evolution of emission and dynamics of the ground state depletion of molecular media. The technique of digital recording and data processing at the sampling rate of 2 gigasamples/s ensures a resolution of single nanoseconds in the time interval of up to 10 μs. The spectrometer has been successfully tested in photophysical studies of the triplet states of xanthione in benzene and n-hexane solutions.
