Abstract :
We propose a new technique for efficient generation of 6 THz near-single-cycle transients though optical rectification of 800 nm fs laser pulses in a DAST/SiO2 multilayer structure. The use of such a composite material allows to obtain phase-matching and control cascaded nonlinear processes.
