    Abstract

    A new scheme for the efficient generation of broadband terahertz radiation by optical rectification of femtosecond laser pulses in the singie-domain lithium niobate crystal, equipped with the step-wise phase mask (SPM) was considered. It is shown that using SPM can provide phase matching for all spectral components of the terahertz pulse by providing effective conversion of laser radiation in the terahertz region. The angular distribution of the spectral components, as well as a temporal form of terahertz pulses in the wave zone was investigated. Results of studies can be used in time-domain spectroscopy, imaging of hidden objects, etc.
