Abstract
We report highly efficient blue-light generation by frequency doubling of a high-power cw diode-pumped 946-nm Nd:YAG laser. A periodically p oled lithium niobate crystal, 6 mm long and with a period of 4.6 mu m, was used in the experiment. 49 mW of blue light was generated with a conversion efficiency of 4.6%. The measured effective nonlinear coeffi cient (d(eff) similar to 19 pm/V) and the temperature-bandwidth (Delta T similar to 3 degrees C) of the crystal are close to the theoretical Limits.
