This paper describes, two kinds of high-light-intensity bulb, one is a mushroom-shaped bulb and the other is a round flat bulb, replacing the usual spherical bulb tor optical pumping. We light these two bulbs with a high r. f. source and carry out the experiments of pumping 87Rb maser with these lamps. The light intensities of the two bulbs are respectixely 2. 3 and 2 times as that of the spherical bulb. And the largest output powers of the maser pamped with these two lamps are-60 and -62 dBm at the optimum resonance cell temperature of 67 and 66℃ respectively. The improvement of short-term frequeney stability of the round flat bulb pumped 87Rb maser is consistent with the increment of the output power of the maser.
