ABSTRACT:
A wavelength conversion device is disclosed. The wavelength conversion device includes at least a fundamental wave light source and an external resonator, where a reflectance Rinof an input coupling element that inputs light from the fundamental wave light source to the external resonator is selected as represented by the equations 1 and 2, when a frequency jitter of the fundamental wave light source is Δfjitter, a resonator length of the external resonator is Lcav, a frequency line width of the external resonator is Δνcav, a total internal loss of the external resonator is δ, and a speed of light is c.Δ⁢⁢vcav=cLcav×1-Ri⁢⁢n⁡(1-δ)π⁡(Ri⁢⁢n⁡(1-δ))1/4(1)Δ⁢⁢vcav≧Δ⁢⁢fjitter(2)
