Short description

Within the framework of the proposed project, the new schemes for generation of broadband THz pulses will be developed and realized based on optical rectification (OR) of femtosecond laser pulses in a singledomain nonlinear crystal, by placing of step wise phase mask in front of the crystal. Step wise phase mask forms a tilted amplitude front of the exciting laser beam, thanks to which the phase matching for all the spectral components of the THz pulse provides. Changing the size of the optical beam and steps of mask can change the shape of the generated THz pulse, its spectral bandwidth, the radiation pattern, etc.
