DOI: 10.1109/tthz.2019.2934717
Abstract: This article studies the effect of titling a beta-barium borate (BBO) crystal on the efficiency of generating terahertz (THz) radiation by dual-color femtosecond laser filamentation. It is found that tilting the BBO crystal can compensate… read more here.

DOI: 10.1364/ome.8.001410
Abstract: We uncover that thin (of few tens of μm thickness) BBO crystal exhibits reasonable transmittance and phase matching in the 3 − 5.2 μm range. We also provide refined dispersion equations of the ordinary and… read more here.
