Paper Abstract

We have demonstrated single-pass frequency doubling of a ps Ti:sapphire laser with a periodically poled lithium niobate (PPLN) waveguide for spin polarization of 3He. Since the refractive index of PPLN varies with tuning the temperature, it is possible to control optimum fundamental wavelength for the second harmonic generation. We indicated that the tuning rate was about 0.06 nm/K. Moreover, we used the SHG light to conduct optogalvanic spectroscopy, which demonstrated that the linewidth of the SHG light could be incorporated in optical pumping transitions for the spin polarization
