Paper Abstract

We present an enhanced scheme of polarization-sensitive THz-ABCD which can provide about twice broader bandwidth than the conventional method. In our experiment using a 26 fs laser pulse, compared with 0.3~40 THz in the conventional scheme, bandwidth coverage from 0.3 to 80 THz has been achieved in the resolution-enhanced scheme. It also should have to be noted the terahertz source may also restrict the detection bandwidth. Employing the polarizationsensitive technology, the polarization in time domain, as well as the field amplitude, can be achieved with just one single scan.
