title: Generation of coherent radiation in the vacuum ultraviolet using randomly quasi-phase-matched strontium tetraborate.
abstract: Tunable coherent radiation is generated in the vacuum ultraviolet down to 121 nm using random quasi-phase matching in strontium tetraborate, the shortest wavelength ever produced with a second-order nonlinear optical process in a solid-state material. Relevant properties of this radiation, the nonlinear process, and the nonlinear crystal are investigated.
