Abstract

Based on the polarization period of 11.73um magnesium-oxide-doped lithium niobate (MgO: PPLN) Crystal, frequency up-conversion of continuous-wave (CW) 1559.5nm signal light has been demonstrated. It is pumped with an actively Qswitched diode-pumped Nd: YAG laser at 1064nm in micro cavity scheme. When operating at the temperature of 110.3 °C, the wavelength of output light is 632.5nm, and the maximum energy conversion efficiency is 1.1×10^-4. The change of the output light characteristic as the operating temperature varies is studied, and the beam quality of the output laser is also analyzed.
