Abstract

We report the first demonstration of VUV light generation through cascaded nonlinear wavemixing using electronic nonlinearities. We also demonstrate a type of quasi-phase-matching in the UV region of the spectrum for the first time. In past work, by using a hollow-waveguide geometry for frequency conversion, we demonstrated that it is possible to achieve high efficiency conversion efficiency (13%) of ultrafast pulses to 267nm using four-wave mixing.¹ We also demonstrated broad-bandwidth phase-matching to generate light from 80-300nm, using both resonant and non-resonant high-order phase matching processes.^2,3
