Results are presented of pulsed optically-pumped polarized H{sup {minus}} ion source (OPPIS) development for high energy accelerators. An atomic hydrogen beam intensity of 2 {times} 10{sup 18} atoms/s within the polarizer acceptance was obtained with an atomic H injector at BINP. A pulsed polarized H{sup {minus}} ion current of about 10--20 mA should be obtainable using this injector. Limitations on beam characteristics due to space-charge were studied. A polarization scheme to avoid space-charge limitations is considered, in which charge-exchange and spin-exchange are combined.
