Abstract

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 obtained by changing the crystal grating periods from 28.5 to 31.5 microns. When the diode pump power is 8 W, the intracavity OPO operating at a repetition rate of 10 kHz produces average output power of 0.42 W, corresponding to conversion efficiency of 5.2% from the laser diode pump to OPO idler output.
