Middle infrared intracavity periodically poled MgO:LiNbO3 optical parametric osc

A periodically poled magnesium oxide-doped lithium niobate (5 mol% MgO:PPLN) intracavity optical parametric oscillator (OPO) pumped by a diode-pumped Q-switched Nd:YLF laser operating at 1.047 microns is reported. A broad continuous tunable middle-infrared (mid-IR) spectrum of 2.69-4.07 microns is o
