High power PPMgLN based optical parametric oscillator pumped by a linearly polar

We have experimentally demonstrated a periodically poled magnesium-oxide-doped lithium niobate (PPMgLN)-based, fiber-laser-pumped optical parametric oscillator (OPO) generating idler wavelength of 3.82 mu m. The pump fiber laser was constructed with a linearly polarized, semi-fiber-coupled acousto-o
