Theoretical Investigation of Backward Optical Parametric Oscillator Pumped by Vortex Beams
Nonlinear generation and manipulation of vortex beams have emerged as a research hot topic in recent years. During nonlinear frequency conversions, orbital angular momentum will transfer from the fundamental wave to harmonic waves. In this work, we study theoretically the backward optical parametric...
