Fabrication Of Periodically Poled Mgo Doped Linbo3 Crystal And Its Application For Optical Parametric Oscillator

Here we report that the propertyies of the poling electrode is one of the most important factors in fabrication of the ferroelectric crystal poling. In this paper, systematic researches on the property of electrode coating and the forms of electrode contact have been made. By using pulse applied electric field, the periodically poled grating of 31.2 mu m was prepared on a 1mm thick 5% MgO-doped Lithium Niobate crystal. A wavelength of 1064nm pulse laser was used as fundamental source to operate optical parametric oscillation experiment, and 1.141W of idler output power was obtained when PPMgOLN pumped by 1064nm of 5.567W at the temperature of 80 degrees C The maximum conversion efficiency from incident pump power to the idler output achieved to 20.1%.
