Abstract
There is a need for improved frequency conversion materials for UV and vacuum UV generation. Currently available materials, such as BBO, LBO, and CLBO, all have significant limitations including solarization, large walk-off under birefringent phasematching, limited vacuum UV transparency, and/or difficult handling because of being hygroscopic. Here, we report on ferroelectric domain inversion in BaMgF4 (BMF). This material has transparency to <140 nm, is resistant to solarization, and can be used for quasi-phase-matched (QPM) interactions, which eliminates Poynting vector walk-off.
