High efficiency mid-infrared optical parametric oscillation in thick periodically poled lithium niobate

Abstract

Once polished and AU-coated, those erystsls have been used to demonstrate mom tempentux optical parametric oscillation (OPO). The above singly-resonant cavity was pumped with a TEM,, diode-pumped NdYAG laser delivering up to 20 ml @iva from Thomson-CSF Laser), and loosely focused to a 850 pm waist at l k 2 ../ "61 oo'---.
