We report highly efficient blue-light generation by frequency doubling of a high-power cw diode-pumped 946-nm Nd:YAG laser. A periodically poled lithium niobate crystal, 6 mm long and with a period of 4.6 µm, was used in the experiment. 49 mW of blue light was generated with a conversion efficiency of 4.6%. The measured effective nonlinear coefficient (deff~19pm/V) and the temperature-bandwidth (ΔT~3°C) of the crystal are close to the theoretical limits.

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 poled lithium niobate crystal, 6 mm long and with a period of 4.6 µm, was used in the experiment. 49 mW of blue light was generated with a conversion efficiency of 4.6%. The measured effective nonlinear coefficient (deff~19pm/V) and the temperature-bandwidth (ΔT~3°C) of the crystal are close to the theoretical limits.
