Abstract
A wavelength conversion system including: A. a first nonlinear optical crystal to which first pulsed laser light having a first polarization state and a first wavelength and second pulsed laser light having a second polarization state and a second wavelength are inputted and which is configured to output in response to the input the second pulsed laser light and first sum frequency light having the second polarization state and a third wavelength produced by sum frequency mixing of the first wavelength with the second wavelength; and B. a second nonlinear optical crystal to which the first sum frequency light and the second pulsed laser light outputted from the first nonlinear optical crystal are inputted and which is configured to output in response to the input third pulsed laser light having a fourth wavelength.
