    "abstract": "We report the operation of a $^{87}$Rb maser in the self-oscillating mode,\nusing a laser diode as the optical pumping source. The maser uses a TE$_{021}$\ncavity surrounding a cell containing the atoms and 11 Torr of N$_{2}$ as the\nbuffer gas. The optical pumping is accomplished by using a commercial laser\ndiode frequency-locked on the linear absorption line of an external rubidium\ncell. The maser output power is maximized when the laser spectrum is spread by\nmodulating its frequency through the variation of its injection current. The\nmaser output power is also presented for various modulation waveforms and\nfrequencies. We find that the spurious sidebands induced by the modulation can\nbe minimized. Finally, the linear dependence between the laser and maser\nfrequencies is shown. We find that the relative maser frequency pulling from\nthe laser is about $4.6 \\times 10^{-3}$.",
