Travelling wave optical parametric generator pumped by a conical beam

For the first time an operation of the travelling wave optical parametric generator (TOPG) pumped by the conical beam is demonstrated. The output radiation of the TOPG consisted of two diffraction-limited axial beams and two corresponding conical beams of different frequencies and polarizations. The energy efficiency was ∼3%, and generation threshold was ∼250 μJ.
