| Abstract: | An optimized all solid state single frequency Nd∶YVO 4 laser at 1.06 μm with a mode cleaner was used to pump a optical parametric oscillator consisting of periodically poled LiNbO 3. The near degenerate subharmonic wave at 2.1 μm wavelength was obtained under a pumped threshold of 1.5 mW. The subharmonic output of 0.9 mW was produced at a pump power of 6 mW. The light to light conversion efficiency is 15%. |
