Experimental layout for a configuration of the dual-frequency solid-state laser and compact THz source. The dual-frequency laser cavities are marked by the dashed border line.
Q-switched output power vs pump power at 1047 and 1053 nm. Dots and squares correspond to data points; straight lines correspond to linear fits to data points.
THz average and peak power dependence on the combined power at 1047 and 1053 nm; straight lines correspond to quadratic fits to data points. Inset is the intensity of the THz radiation as a function of the azimuthal angle of a THz polarizer.
THz power at , generated by mixing dual frequencies from Nd:YLF and Nd:YAG lasers, being transmitted through a Si etalon as a function of the displacement between two Si wafers.
