Recently there have been many important advances made in spin-exchange optical-pumping (SEOP) polarized He-3 targets. Use of hybrid K-Rb SEOP achieved He-3 polarizations near 50% in-beam during the recent JLab G{sub E}{sup n} experiment (E02013). Combining well-optimized alkali-hybrid SEOP with high-power spectrally-narrowed laser diode arrays increases He-3 polarizations to 70%. We describe how these technologies work and why they improve target polarization.
